In many years (34+) of trying different ways to start a heat sunk car....I have found that it is always the starter Now I know you disagree with me on the solenoid issue But, try holding the positive cable after you try to start a heat sunk car,,,You will get burned...By moving the solenoid to a different area you are now adding more battery cable to and from the solenoid, This will take a big draw on the battery and will not help the starting issue...I have reached uder my car many times with the key in the on position and jumped the solenoid and the car will start, But all I am doing is by passing the draw from the key to the solenoid...Trust me, a remote solenoid will not cure a heat sunk car, it will still heat sink....Do as banshee says and get a GOOD rebuilt starter and a hi performance (stock looking)solenoid (I think AC delco makes one) and you will have no problems...I suggest you bring your starter to a good rebuilder and NOT your local parts store and tell them your issue they will solve your problem...And I bet they will say to never run a remote solenoid....I have pics of my Ram Air car that always heat sunk with a remote solenoid and pics now without it and it has never failed me...I do also know that over the upcoming years of heat on that starter it will do it again...Well the first sign of that, It will be rebuilt again...It's called life in a Pontiac.
[quote=Claus Moeller]If any car has heat sink problems -in relation to the starter, -a remote solenoid will resolve that problem..
-No difference in draw in relation to stock solenoid (on the contrary).
-If wiring harnes burned, -then it was shorted somewhere.. (possibly wire from remote solenoid to starter on the headers).
Here is an article about remote solenoids / heat sink problems:
I have taken my starter to a reliable starter rebuilder. And had the best of every part put in the starter and the best solenoid. Still after a few months the solenoid is toast.
