There's a GOOD reason for that. E-12 S & E-15 AA to GA don't HAVE
an RTN relay. The RTN functions are contained in the silicon
skulduggery on Card #1.

Sounds like it is "on", meaning that the tractor will not drive. Just my thought.

Fwd rev relay clicks back and forth, but no power drain. PTO lights lift all work Have manuals but haven't deciphered the troubleshooting diagrams. Part of the problem is lack of labeling on the machine jumped out the brake and seat switch to test. no dice hints welcome................ _______________________________________________ Elec-trak mailing list Elec-trak cosmos phy tufts edu https://cosmos.phy.tufts.edu/mailman/listinfo/elec-trak |
