170 gasser ?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   My 170 gas has puzzled me. Repaired replaced alternator. Repaired voltage regulator harness. Replaced voltage regulator. Worked great. No problems. A couple months later, will not click or try to turn engine over. Would not jump across post to energize solenoid. What could cause the drain on battery? Could new regulator be stuck and drain it? Thanks, Tracy

	your going to have to run a few tests.. Battery could be bad.. alternator could have internal short... voltage regulator could have contact STUCK and being grounded... and then any of the wires between them could have a problem... I would start with a fully charged battery.. disconnect the + cable and let tractor set for a couple days.. reconnect and see if battery went dead on its own, or has full charge... Get a amp meter in the line and see what is being drawn out of battery when setting with the key off....... if battery is good, start looking at the alternator / regulator / or even the starter motor... Is any of them feel WARM to the touch ?
	Like them all, but love the "B"s.

	Steve, battery is almost new. Alternator checked good. I put a new regulator on it, but I wouldn't swear it is good. Ain't like the old Neihoffs . My meter was dead today, low battery. I will charge up the battery and test from there. Thanks, Tracy

	Pull one of the battery cables off in the dark and slightly touch it to the post you pulled. If there’s an any slight spark there’s a draw. You can tell by the size of spark how bad it’s drawing. Newer vehicles have a draw all the time (that’s why they don’t sit as long with a charge). I don’t think alternators are supposed to have a draw… I will start pulling wires and check for spark until the spark goes away and chances are that circuit is possibly the problem.
