B16HBG 0 Posted December 30, 2007 Hi guys, My peugeot 205 mi16 is on its third set of ht leads in less than 2 miles. After the ones that came on the engine were arcing along the cam cover i ordered some new CI ones and put those on, it made it better but after about a mile or so they started arcing again. I decided to order some heavy duty megaleads and put those on but again after a mile or so they started arcing. I've put an earth from the cam cover straight to the battery negative but hasn't helped. I need some ideas because i'm clutching at straws now. I'm tempted to order some magnecor leads but not sure whether to bother if its gonna happen again. I'm even gonna spray the cam cover in a different colour as its sprayed in metallic red VHT, i know it sounds stupid but i'm all out of ideas now. Any help would be greatly appreciated as i've searched high and low round the forums and have had no luck. Thanks Henry Share this post Link to post Share on other sites
Tom Fenton 1,526 Posted December 30, 2007 Is one of your spark plugs high resistance causing the HT to track across the lead as opposed to jump the plug gap? I'd try a new set of plugs before buying more leads. Share this post Link to post Share on other sites
B16HBG 0 Posted December 30, 2007 Plugs have done about 40 miles maximum, but when i get it to work on wednesday i will have them out and clean them up but wont be able to gap them as they're quad or twin electrode i seem to remember. Think i'm gonna order some splitfire leads tonight, anybody used them before? Share this post Link to post Share on other sites
Rom 0 Posted December 30, 2007 Theres another problem somewhere, there is no way 3 sets of leads have failed,without some help Is it always the same lead arcing ? or is it all of them ? Is it arcing right near the boot ? Try insulating the lead with tape,not a cure,but might help with diagnosing. I cant help think something is wrong, plugs, coil, leads,there all definately right ? Something must be wrong,ive seen a set of leads break down, but not 3 new sets. Share this post Link to post Share on other sites
Mikey S 29 1 Cars Posted December 30, 2007 are you sure one of the sparkplugs are not cracked on the ceramic part? Share this post Link to post Share on other sites
DamirGTI 327 Posted December 30, 2007 (edited) Hello ! Last time I've had problem with current leaking (arcing) from the main coil HT lead to earth - it was the ignition module i know it's hard to believe but it was .. however it wasn't just arching/current leaking (was a big "King Kong" blue arc visible at day light together with strong clicking sound..) , the engine was misfiring and cutting out as well , all in the same time ..

B16HBG 0 Posted December 30, 2007 I've only put 2 new sets on, the others were original with the engine. its usually on plug lead 1 arcing wear it lays against the cam cover but i've put electrical trunking around each individual lead but its still arcing somewhere that i cant see. I'm thinking that there may be a problem with the plugs not getting a decent enough earth in the head, gonna take them out on wednesday at work and clean them up. is it possible the coil could be over powering the leads? its probably the only thing on the car electrically that i haven't changed for new but i have a spare which i've tried but does the same Share this post Link to post Share on other sites
B16HBG 0 Posted December 30, 2007 Damir i've changed the ignition module/amplifier to cure a different problem with it not being able to go over 3000rpm and it worked. I have done about 30 miles on most of the components as i havent been able to drive it with the problems i've had. But this is the last problem and i can't solve it or at least having alot of trouble attempting to. Share this post Link to post Share on other sites
DamirGTI 327 Posted December 30, 2007 I've tried full bag of leads , new and spare ones - none of them didn't help fixing this ... The way i understand this is - when the ignition module goes crazy then he overloads the coil secondary badly and voltage output goes up , way above the standard voltage and standard voltage requirements , and this in the end results in current leaking/jumping from leads , lead boots to earth ... Id check all ignition system starting with the : dizzy cap , rotor arm , coil/coil tower , ignition amp. ... Damir Share this post Link to post Share on other sites
Pugnut 9 1 Cars Posted December 30, 2007 the only thing i can think of that would push the coil secondary voltage higher would be a short on the primary side . this would increase the ratio of the transformer and up the output voltage dramatically . Obviously earth faults can do all sorts of weird and wonderful things i wouldnt know the resistance values offhand but if you post up the measurements i'm sure someone would help.

Dave G 0 Posted December 30, 2007 had a similar problem with a group a cil on my escort, turned out to be a combination of plugs and a bad earth through the timing sensors and ecu but not sure exactly which as i changed the plugs and did the earth at the same time Share this post Link to post Share on other sites

DamirGTI 327 Posted December 30, 2007 (edited) Well I'm sure that you can order (if they don't have one in stock..) ignition amp. for this car from your local car parts store OE Peugeot part numb. for ignition amp. is - 5945 48 (it doesn't matter if its 6 or 7 pin amplifier , both of them will work ) Bosch - MTR01 0227 100 123 Magneti Marelli - MTR01 94003 8501 Valeo - CD856 245510 Huco - 138001 Ducellier - MTR01 521 013D Beru - ZM001 Lucas - DAB201 54403549 Just read the code/numbers to the guy at the shop (OE numbers or Bosch numbers or any other ignition amplifier numbers which I've write above ..) and he will find you one , it doesn't need to be Bosch just don't buy that Intermotor amp. again ! as for the prices (for which i know/remember..) : the OE amplifier (Bosch 123) from Peugeot is around 80.00-88.00 (from car parts store this Bosch 123 amp. must be a few pounds cheaper ..) Valeo (from car part store ..) is around 70.00-75.00 Huco (from car part store ..) around 30.00-35.00 Cheers ! Damir EDIT : or if you don't want to buy new ignition amp. - go to scrapyard and find a spare one from 205/309/405 car .

B16HBG 0 Posted January 1, 2008 Thanks damir, i've located a lucas dab201 on ebay so i think i'll have a bid on that hopefully solve the problem. might be worth investing in a new coil aswell. when i take it into work tomorrow i'm going to put it on the crypton diagnostic centre and test the output of the coil but firstly i'll change that amplifier i think Share this post Link to post Share on other sites

B16HBG 0 Posted January 5, 2008 hi guys, have replaced the amplifier with a lucas dab 201. I drove it last night and it hasn't improved but could that be because the leads are already knackered if the problem was the amplifier in the first place? I'm unsure whether i want to purchase a new set of leads if its just gonna ruin them again although i can always say they're faulty but how many ht lead companys are there i can do that to lol. I need to source a decent ignition coil, has anyone got one for sale or advise a decent make/part number? I've got two but the chances are they are no doubt faulty. I'm sure that once its running fine it will be great but i'm somewhat questioning in my brain why i didn't just keep the standard jetronic system as i knew it was working. Has anyone got any test data for the coil and amplifier as i would be interested to see what readings i will get. Any help i am incredibly grateful for just cant wait to get on the road with it now!

B16HBG 0 Posted January 5, 2008 Could a knackered ignition amp really kill HT leads that quickly though? I have no idea chap, i've never seen it before in my occupation but lots of people on here seems to think it might. In my mind an ignition amp amplifies current so if it is amplifying a current that is too high then the coil will produce current through a ht lead which just cant be handled. Please tell me if i'm wrong but i think i'm on the right lines Share this post Link to post Share on other sites

B16HBG 0 Posted January 6, 2008 Hi guys, obviously u know i'm still having trouble after fitting a new ignition amp/module. After reading a few posts on hear i'm starting to think that maybe there is a rotor arm problem? it has had a new arm and cap but this was about 5-6 months ago. bear in mind its only done about 50 miles since then but as its been standing could the item perish? help help help! lol. really wanna experience this 160hp beast!

DamirGTI 327 Posted January 6, 2008 (edited) Hi ! Strange ... , did you try with another coil ? When the leads starts arcing does the engine starts to misfire hesitate or something ? or it drives fine when this arcing appears ..?! Also does this arcing problem appears only when the engine warms up , or it's the same - hot or cold ? Cheers Damir Edited January 6, 2008 by DamirGTI Share this post Link to post Share on other sites

Cheers Damir The engine misfires at idle when the leads start arcing, then approaching 3000rpm under load its fine after 3000 it struggles and starts to misfire spontaneously until it reaches about 4500 then all of a sudden the revs just shoot up as if nothing is wrong. its the same hot and cold Share this post Link to post Share on other sites
DamirGTI 327 Posted January 6, 2008 (edited) Hi ! Well this does sound like the same problem which i had a year ago ... was very similar .. and as said before in my case it was the ignition amp. (more precise - was just the thermal transfer paste at the back of the amp. , was dried out and simply removing the amp. and re-applying the paste has solved my problem ..) However if you say that you've fit another ignition amp. that doesn't helps us so much ... umm try with another coil Im running out of ideas Damir Edited January 6, 2008 by DamirGTI Share this post Link to post Share on other sites
