Okay it has to be a 6x4 as they didn't make a 6x2. All four rear wheels are driven. Without a wiring diagram the next step would be to check the keyswitch.
No fuel solenoid so we want be hearing it click either.
TCA22740 (INDAK 4A463A)
Make/Break Table for continuity checks.
B = 12v all the time
G = Ground
M = Magneto Kill. connects to G in the off position along with A.
A = accessories. Has 12v on it when the switch is in the run and start positions.
S1 and S2 is the starter wires should 12v on them in the start position with S1 or S2 being 12v in run position.
Checking here would verify battery voltage at the "B" terminal and is making sure that switch is working otherwise. IF things are there then go to the starter solenoid and check the small for 12v when a helper is holding the keyswitch in the start position. IF present and the grounds are good then it is the starter.
Hmmm, I don't have a single one of the switches in stock. Time to order one for stock.
