pugbliss 0 Posted May 1, 2007 hi what are the syptoms of when a coil breaks down under load also what are the syptoms of when an ignition amp does the same. cheers Share this post Link to post Share on other sites
welshpug 1,627 Posted May 1, 2007 coil=misfire, especially when warm. amp=nospark. Share this post Link to post Share on other sites
Ahl 4 Posted May 1, 2007 Thats right, but the amps usually start to misfire too, starting at high rpm, then gradually getting lower. Share this post Link to post Share on other sites
Anthony 1,000 Posted May 1, 2007 Failing coils generally give misfire/stuttering under load, usually worse when warm Failing amps generally give a misfire (often almost rev-limiter like) at higher revs, typically starting around 4000-4500rpm in my experience. Complete failure of either will give no spark. Share this post Link to post Share on other sites
Super Josh 4 Posted May 1, 2007 Failing amps generally give a misfire (often almost rev-limiter like) at higher revs, typically starting around 4000-4500rpm in my experience. This often happens when the thermally conductive paste on the back of the Amp. dries out, and the Amp. starts to overheat. Josh Share this post Link to post Share on other sites
pugbliss 0 Posted May 1, 2007 ah i see . well thats what im getting( slight missfire/jump /hessitant on motorway feeling ) better get new ones very soon. best place to get them anyone...cheaply??? Share this post Link to post Share on other sites
hodgy 0 Posted May 9, 2007 ive got the same problem. mine feels like limiter is coming in at 5500rpm n mine is on carbs n i have no limiter how do you know if its a 5 pin or 7pin module? sounds a silly question like Share this post Link to post Share on other sites
pugbliss 0 Posted May 11, 2007 i would take a wild guess and count the tabs on the conector part of the old module you will be replacing??? Share this post Link to post Share on other sites
hodgy 0 Posted May 12, 2007 ive changed my amp n its a lil better.my mate got me the wrong coil (phase2) so once i change that i hope its better cos its only been funny since i fitted my 285 cam tho Share this post Link to post Share on other sites

hodgy 0 Posted May 17, 2007 ive changed them all and its still no better!!! but it could also be my carbs that need re jetting as the valves are open longer now so need more fuel Share this post Link to post Share on other sites
Rob_the_Sparky 9 Posted May 17, 2007 ive changed them all and its still no better!!! but it could also be my carbs that need re jetting as the valves are open longer now so need more fuel Sounds like a somewhat non-standard car so you may well have a different problem.

huzzer 0 Posted May 17, 2007 Ive had a problem with mine for weeks! Changed the ignition amp twice and it made no difference. The two that I changed were unipart ones. As soon as I put a Bosch amp on it was fine. They dont seem to like non bosch. Share this post Link to post Share on other sites
Rob_the_Sparky 9 Posted May 17, 2007 Ive had a problem with mine for weeks! Changed the ignition amp twice and it made no difference. The two that I changed were unipart ones. As soon as I put a Bosch amp on it was fine. They dont seem to like non bosch. But I've had a non-BOSCH on my 309 for a while, since the old one blew and apart from needing a new coil as well then it has been fine (dying coil and ignition amp had the same symptoms...probably because the coil killed the first one but I can't prove that 100%). Quite likely the duff coil blew the ignition amp in the first place...I'm using a GSF ignition amp that also have a reputation for being a bit iffy. Have you replaced your coil?

pugbliss 0 Posted May 18, 2007 ive looked into the diffrent ignition amp ( bosch and after market) and there seems to be a big price diffrence. after market = £27 ish (gsf) bosch = £ 66 ish (price from pug dealer) erm what do i do? Huzzer.... where did you get your bosch amp from??? Share this post Link to post Share on other sites
hodgy 0 Posted May 19, 2007 ive got a brand new coil from gsf and an amp cost me £55 for both but might try source a bosch one. what annoys me with mine is the car was fine before i put the new cam in now its slower cos i cant rev past 5500 rpm Share this post Link to post Share on other sites
