76 W100 no start, no idea
I've got a '76 W100 318 that will not start. The truck drove a few months ago and then all of a sudden when i hit the ignition button it didn't do anything. The starter refused to turn the flywheel so i replaced that, didn't work so i replaced the starter relay, didn't work so i had the battery tested, all good, full charge.
Brand new starter, relay, battery, ignition coil, distributor, and ballast resistors, but when i try to start the starter simply makes a single "thunk" sound and thats it. Even when i short out the terminals on the starter with a screwdriver it does the same things, "thunk" and no turning. Right now its a very expensive lawn ornament and i don't know much about the electrical systems in older vehicles. If this questions has been ask/answered in the past then i apologise for double posting. |
crazy question, but have you traced aaaaaaaall the wires to make sure they are good and tight? any fuzzy stuff up by the battery terminals? sounds like a loose or corroded connection to me.

hmmm may be best to bench test the starter then, to be sure. these issues can be a bear but there's only so many things that can be wrong, so hang in there!

Put a Socket and a Breaker bar on the front crankshaft nut and see if you can turn the engine over?

lol good ole hog, with great advice. yeah. no use trying to trace a starter issue if the engine is seized. :D good call, man.
