Well I'm back - and so is the problem...
Here's what I've done so far,
Things to still try - Remove all ground wires from post on the block, clean and reinstall? Swap slave solenoid with other engine?
- Replaced both batteries that start the Stb Engine - still have the problem (yes I did clean the cables and posts before installing)
- Swapped starter motors between engines, cleaned all disconnected wires before reinstalling - still have the problem with Stb engine ONLY (rules out a bad starter since I have yet to have the problem with Port engine)
- Removed/tested/reinstalled slave solenoid by applying power to smaller posts and checking larger two posts for continuity, seems to work just fine every time - still have the problem.
- Tested starter switch by removing yellow/red power wire (that powers the slave solenoid upon starting), showed full power when starter button depressed every time - still have the problem.
- Tested yellow/red power wire connected at the starter by disconnecting it then testing for 12vt upon depressing the starter button, works every time - still have the problem.
Any suggestions??:huh:
OK, Problem seems to have been solved - Here's the update.:smt038
Swapped the slave solenoids and took all the ground wires off both blocks, cleaned them well, reinstalled. The ground wires were a bit corroded (more on the engine that never had a problem though) which seems to have been the problem.:thumbsup:
If the slave solenoid was bad, the other engine would now have the same problem - which it doesn't. (so slaves are ok)
Moral of the story?? Problems with DC electrical - check your grounds!!:grin:
Thanks everyone for your imput.
