problem question

[yackboy49]

202 motor,battery seems ok, that is, it  fires up after sitting for a few weeks, however, on the weekend, after a 60 kilometer trip, starter motor would not engage, ignition light on, then turned to start, but no starter motor, quick push and away I went, rest of the trip when I stopped, everthing started ok... Done this once before, and started ok after about 30 minutes. Could it be the coil to hot ? or condensor ?....can the battery overcharge ?....Battery is in the boot.

           It could be your starter motor is getting to hot (normally only old starter motor does it). Are you running standard exhuats, header's or what set up do you have. This problem is more commonly found with ford's but have had it happen on Holden's before. If this is the problem just make up a heat shield that goes between the starter and the offending exhuast pipe. This only has to be thin metal 0.5 to 1mm as it's design is to disapate the heat not hold the heat in that area. If you know anyone with a XD Ford have a look at the heat shield on their starter motor and you will see what I am suggesting.

Another thing to look at is there may not be getting enough volts to starter coil.  Put a relay in to make sure voltage drop isn't your problem.

Thx for the info Tumbles & Sarge,

running headers,

what would cause the voltage to drop at the starter ? would it be the distance from the boot ?

thxs again

             The greater the distance from the starter to the battier, the more voltage drop you will have. You could try increasing the cable size.

 Voltage drop from the wire from the ign switch to the back of the starter motor coil can happen for different reasons, if you have good volts to the back of the starter motor (main supply) you can tee off it to a relay and use the starter wire to operate the relay and run a wire back to the start soleniod. But remember this will only work if you have a good supply to the back of starter...

 thxs Tumbles, I have a faint suspicion my problem  is heat related, when I look back at when it has happened, it was when the car was driven hard or worked hard in the heat.
