REFLECTOR: Starter contactor

Thu Jul 18 10:19:46 CDT 2013

David,

I takes about 15' of #2 to supply starter current from the battery up front 
to the engine compartment so it doesn't matter which end the starter 
solenoid is connected to.  Same wire same weight.  My starter solenoid is up 
front for a reason.  That #2 wire is hot all the time your master is on and 
if something comes loose and shorts it to ground, big trouble.  With the 
solenoid up front it is only energized during start and can't give you any 
grief once you're up and running.  It won't work any different with either 
configuration but I think having the solenoid up front is safer.
