My old 773 just let me down. Battery is strong (12.9 volts), turn key to start position and sometimes get clicking sound, sometimes nothing. Starter doesn't engage. Removed starter and tested off machine turns over fine. Any suggestions?? Tks. Dave PS I added a ground cable from neg post on battery to casing of starter .
On the starter there should be a small wire by itself on the solonoid, this is the energize wire from the key switch. Remove the energize wire and check it for voltage with a volt meter when the key is put in the start position. Most likely you will find that the voltage is low (less than 11 volts) at the energize wire causing the problem you describe. This can happen from a poor connection at one of the various plugs the energize wire goes through or the key switch. To test the theory you could test the starter in the machine by crossing the energize wire to the battery terminal, if it cranks over every time that is another indicator the energize wire has an issue. Thanks and let me know if you need more help.
I shorted the energize wire to the pos battery cable and the starter still would't engage ( key on but not in start position.
Hello, maybe i didst clarify. The terminal on the solonoid were the small wire connects needs to have a jump wire hooked to it, then touch that to the big battery post. Sorry if i wasn't clear. Thanks and let me know if you need more help.
I unhooked energize wire, it showed 1.85 volts with key in start position, 4 volts when re-connected. I have no more "clicking" sounds, but selenoids buzzing, 1 on left of motor, 1 on the right. Battery still shows 12.5 volts. When I sit in seat and turn key to start, there is clicking behind left shoulder??
The click behind you left shoulder is probably a relay for the energize wire, find the relay then trace the energize wire to it. Once you have done that test the relay output to the energize wire and see what you have. The relay will have a most likely have a battery hot, a ground, the output/energize wire, and a wire that comes live when the key switch is turned to the start position. The large battery hot is what feeds the relay and the energize wire when the key switch is turned to the start position. Check all this out and let me know if you need more help.
