Possible Engine No Crank' Cause


I'm a newbie to this site and, with winter set in, took some time to cruise the forums. I noticed a number of "my engine won't turn over" posts and thought I'd share my experience. I have a JD 170 lawn tractor (1985?) and had a 2001 New Holland 33hp tractor. Both, after a few years, developed similar annoying starting problems. Intermittently, both would just click when you turned the key. Do it enough times and they would eventually start just fine. On very few occasions, the NH would blow the main fuse. Batteries and electrical circuits always ok. To make a very long and frustrating story short, like all new power equipment, both have several safety switches wired in series in their ignition circuits. Over time, dirt and weather gets into the switches causing a tiny voltage drop across the switch. Have enough switches and you'll wind up with too little power to throw the starter solenoid. I suppose you could bypass the safety switches but that would be, well . . .unsafe. What is needed is a relay circuit that allows them to do their thing without directly affecting the starting circuit. JD actually had a retrofit relay kit and an internet post gave me the diagram and parts for the NH tractor. Never had a problem again. The relay needs to match the specific machines so I can't offer a part number, but sure wish I learned this a lot earlier.

That is why it is normally part of the tune up to check all switches,and clean all cables and ground points,as well as connections in the wiring harness.
The best way to keep this from happening,is to use Dialectric grease in all connections,and switch connectors.
You can get the Dialectric grease from any auto parts store,or even Walmart stores.
