From: michael.janket on 6 Dec 2008 15:17 My 1987 Honda HT3813 tractor won't start. I have a new battery and new solenoid. I turn the key, get a click. Sequentially, where do I start the diagnosis process? Do I have a broken wire that won't deliver enough juice to the solenoid? Do I jump from battery to terminal with another wire? Do I splice in another wire from the starter switch and attach that to the small in terminal in the solenoid that carries a smaller voltage from said switch? Must be a simple way to piece this together, suggestions very welcome. Gotta be simple. thanks all, Mike

If the starter solenoid clicks rapidly several times, that indicates a weak battery. The best way to find out whether the solenoid contacts aren't making good connection is to jumper from one big terminal to the other. If the starter cranks, it's the solenoid. You can also jumper from the battery directly to the terminal on the starter, if it's accessible. If the starter cranks, the problem is somewhere in the cables, perhaps just a bad connection at the battery, solenoid, or starter. One problem which isn't obvious to most mechanics occurs when the engine block corrodes and the starter can't make a good ground to the engine. And, if there is a ground jumper from the engine to the chassis, make sure that's making good contact.

Before you get too carried away with the other stuff, listen for a whine after the click, which would indicate a failed engagement mechanism OR a stripped gear on the starter. Also WATCH the flywheel. If it tries to move just a little bit and stops, that could be a sign of a seized engine.

Gotta be simple. thanks all, Mike If the solenoid is clicking, you're getting juice to the solenoid. I'd check the connection from the solenoid to the starter motor itself next. Easy check is to run a length of starter cable from the battery to the starter motor itself. If it spins, the problem isn't the starter motor, but the wiring between it and the switch or, most likely, it and the solenoid. -- BMW K1100LT Ducati 750SS Yamaha XTZ660 Tenere Honda CB400F CB250N SH50 chateau dot murray at idnet dot com "What you're proposing to do will involve a lot of time and hassle for no tangible benefit."
