Got a new switch in a few days form this site and installed it this weekend. It cranked up an ran fine for about 5 minutes and suddenly stopped. Went thru my usual carb tap,check for spark, cleaned dist to regain spark, finally jumpered the switch terminals and it runs. Removed switch and am back to hotwiring to start. Switch shows continuity/no continuity depending on key position while holding switch. What am I missing? [Reply]   [No Email]

Been working good for 2 years. I stayed with a key switch cause I wanted it grand kid safe. I just don't turn to start with it. Still have to press the switch by the shifter.

How about your local motorcycle shop? I know a lot of older bikes used a 2 wire switch and were decent quality and, for obvious resons, waterproof. I"d get one for a street/trail bike. Good luck.   [Reply]  [No Email]

The quality of the aftermarket switches is abominal. It is not uncommon to have a new one fail within hours or even minutes. Go to a GOOD auto parts store and buy a decent automotive ignition switch and you will be good for 25 years or more. Dean   [Reply]  [No Email]

The switch fell apart into pieces in my hand when I tightened a connector. If theres a NAPA number for a 2 wire keyswitch, please post it! Bill   [Reply]  [No Email]

That said. most ignition switchs intended for a late 40s, early 50s vintage pick up truck should work nicely. Dean   [Reply]  [No Email]

Get a jumper wire w/ alligator clips on both ends. (tip # 50) As soon as the tractor stops, put the jumper wire on it. If that doesn't work, move on to the troubleshooting steps ericlb suggested. Or just assume your first test was adequate & buy another switch as TOH suggested. 50 Tips   [Reply]  [No Email]

From the description it may be a heat sensitive failure that only occurs when the switch warms up after the tractor has run for a while. I'd get a new switch. TOH   [Reply]  [No Email]

Got a new TISCO key switch - it was faulty. They sent a new one the next next day (it worked fine). If it happens again, I'll install a heavy duty toggle.   [Reply]  [No Email]
