Morganic 22 #1 Posted September 13, 2022 (edited) Hi Can anyone please point me in the direction of a wiring diagram for a C-125? Mine has been botched -the starter operation with bypassing the solenoid. I would like to get it back to original. It works ok at present but I think solenoid is shot and it’s been bypassed using a isolation switch. Thanks. Edited September 13, 2022 by Morganic Share this post Link to post Share on other sites

953 nut 56,548 #3 Posted September 13, 2022 (edited) From your Battery "+" terminal there is a cable going to a large terminal on the Solenoid. From the same terminal on the solenoid there is a slightly smaller RED wire that goes to a 25 amp fuse and then to the "+" terminal of the Ammeter. From the ammeter "-" a LIGHT GREEN wire goes on to the "B" terminal of your 103-990 Ignition Switch. From the "S" terminal of the ignition switch a small RED wire will go to half of the PTO switch and the RED wire will continue on to the clutch switch. From the clutch switch a RED will continue to the small terminal on the Solenoid. From the remaining large terminal of the solenoid a large cable will go to the Starter. Hope this helps you visualize your wiring. The attached starter system wiring from a 1988 308 is quite similar.
