This assumes that the circuit and battery are 'healthy' and the starter motor is at fault only, understand? Turn the headlights ON and note the brightness, get in the car and attempt to start, do the lights get dim immediately and noticably or go out completely? If so, the starter is at fault. I would then opt to buy a mini starter or get a heat shield and fabricate one for your application or buy the wrap up thermo sleeve which can be wrapped without fabrication. The smaller Nippendenso is the way to go, there draw less current than the original Chrysler starters and are more resilient to heat then they are. In series simply means part of the circuit where current stays the same in all parts of the circuit. Across the circuit is just measuring at that point, in between the leads, or the load itself but you already performed that test..
I have the exact same setup in my truck! A Nip mini starter with Hooker Headers on my 360. It butts up against the starter tight. No problems in 9+ years. The original starter lasted 6 weeks. I got mine from mancini for around 140.00 bucks.
Hi again,
Ok firstly thanks Eddie n Fal for your info!
Ok, here we go, i managed to take the starter off tonight, don't know how i got it out but i did, you were totally right about the headers, didn't think it was going to come out, had to force it between the torsion bar, tie rod and header LOL,. Anyway its out, and first problem noticed that maybe related was the positive post going into the solenoid was slack!
Then i done the test shorting out the starter, to my horror it worked, so i done a repeatability test and it kept working, so i thought the problem was elsewhere. Not totally convinced, i done more tests, then all of a sudden nothing, then more tests, and again nothing. So the problem was intermittent. This was exactly the symptoms, when i ran the car, initially started, got to full temp then would work, then eventually total failure, well to percentage it i would of said 95% didn't work 5% worked.
Now i have a dilema i found a place that rebuilds starters don't know what it will cost as they will need to diagnose the amount of problem, but now i'm thinking of the suggested mini starter route. My question is, is there anywhere in the UK that supplies these NipponDenso starters, as it may pay me to get one rather than spend on the old unit and struggle to get it back in?
Could you tell me what the silver square unit i'm holding is for in the pic below? I think the other item is the starter relay, is this correct, please see pics below, thanks
Cheers Daz
