The yales i work on have their relays up under the dash on the left hand side under a plastic or metal kick plate cover- hope it helps
I replaced the 2 plunger switches, and the problem was resolved. I think when the switches are in the normal position, (up), they are grounding the 4 wire soliniod on the transmission, and this soliniod might act like a relay closing the cqt. to the start soliniod. I can't seem to locate a start relay on the machine.
7777- I'm not familiar with your exact machine but from your description I would believe that the 2 micro or plunger switches would act as a nuetral safety switch- I haven't seen a 3rd switch or the use of the solnoid on the trans for this purpous as of yet. Does it start in both frward & reverse?
