Folks,
Having some electrical problems with my '78 446 and could really use some help. :headscratcher: Here's what I'm seeing:
1. When I turn the ignition switch, nothing happens. Even when I jiggle the travel control and PTO levers, there is no change.
2. Battery shows a full charge when placed on a charger
3. Ignition switch and solenoid are brand new
4. Best I can get is the solenoid to hum when key is turned and charger is placed on battery
5. Starter barely turns when battery is on charger and I bypass the ignition switch using the old "screw driver on the solenoid posts" method.
6. Starter and ignition system worked fine about a month ago and the tractor hasn't been used since
I have looked at the schematics and have checked what I think to be the likely suspects with the notable exception of the neutral safety switches. I know generally where the switches are located, but, how do I gain access to them? Do I have to remove the motor and hydro tank just to get to them?
I'll be the first to admit that electrical problems are not my strong suit and I know this is about as easy an electrical system as you'll find, but I'm growing frustrated. I would really appreciate some assistance from the pros here.
Many thanks!
