Contacts in starter soleniod burnt
Tony Radford Tony the contacts inside the soleniod are cooked from low voltage and high draw( ampage ) of the starter. Need a new soleniod to start. What kind of of starter are you running? Does it have a soleniod on top of the starter motor? how is this hooked up? The internal starter soleniod could also be cooked for low voltage/high amp draw to crank the motor. Do you have a picture of the soleniod, starter connection and the battery location and cables?? From what you are saying and having checked out the battery and Alt, you have a connection problem with a ground or power cable. There is nothing else. The other thing is get a cheap volt meter and wire it into the pos side of the battery where you can see and road test and watch the voltage numbers, They should be in the 13.7 to 14.2 with the motor running at better than 1,500 rpms. The last thing I can think of is the IGN switch is turning off power to the alt wakeup curcuit and the ALT stops charging. There is a test for this. Need to be sure that there is a voltage reading to the Alt. I don't know how many wires you have going to the Alt. There should be 2 min unless you have a single wire that needs a motor to rev over 2,000 rpms to turn on the Alt. Could be more or less if you have under driven pulleys. You didn't get back to us on this question??? starter soleniod are about $12.00- $15.00 dollars ar pepboys. if you cut the rivet the hold the small steel plate to the back of the starter soleniod you can sse if the plate of 2 terminals are burnt. Old trick is to loosen the 2 main studs and rotate them 180 degrees and retighten. You can clean off the contact plate and reuse the starter soleniod for another 10,000 starts. It works, have do this on a 4X4 trail run. Water proof the plate with RTV and reinstall 4 small rivets. I am starting to think that your Alt needs a curtain min rpm range to charge, anything below that and it just stops charging. New GM trucks have this low charging system after the battery is fully charged with low drains on the system. It drops down to about 12.7 volts. Use to improve MPG's. I think is hurts spark output from coils and makes them run hotter. That's another story. Rick L.
