B16HBG 0 Posted March 7, 2008 Hi guys, recently posted about my mi16's arcing issues. just to refresh memories, i put 3 sets of ht leads on the car and replaced pretty much every other electrical component that controls the ignition system and still the leads arced. now on tuesday i measured the ignition coil supply voltage and it turned out that it was running battery voltage with ignition on and then charge voltage with the engine running. So i decided to put a ballast resistor in the circuit and that solved the problem. Unfortunately the day after i went to work in it and it broke down on the way. I pulled up to a junction and it cut out and wouldn't restart. I discovered the problem was down to the coil, it wasn't making a spark. I changed the coil and it worked. Haven't driven it since then. My question is, after fitting that ballast resistor the coil has broke so would it be because of the resistor? or just chance? I'm taking it to work tomorrow and i plan to do some work to it and see if i can locate the problem. Has anyone experienced this before? Also i've only ever seen my mi16 engine so i'm not even sure if there should be a ballast resistor in the circuit, does anyone have one in there mi16?

DrSarty 90 1 Cars Posted March 7, 2008 Mine never had a ballast resistor. Ignition amp, ECU, coil & dizzy all interconnected - nowt else. Good news as you probably know is that coils are just £15. But the amps can be both temprimental (sp?) and expensive. What about your good old loom multi-connector in the engine bay; they're crap! Share this post Link to post Share on other sites
B16HBG 0 Posted March 8, 2008 Managed to identify the cause for the engine cutting out. There was a wire on the loom that had lost all its insulation and was arcing out on the body. I found this out because i got the car running and then shut the bonnet and it instantly cut out. I don't think there was anything wrong with that coil in the first place Share this post Link to post Share on other sites
Tom Fenton 1,548 Posted March 8, 2008 Don't like the sound of that!!! Wires that loose all their insulation usually do so as they have got really hot, and are about to set on fire................ Be careful. Share this post Link to post Share on other sites

It doesnt look like its burnt its insulation off just looks like its been rubbing against the sharp edge of the body, gonna re solder the wire and join soon Share this post Link to post Share on other sites
