MF 1240 Safety switches and relay

Kenzepp · Feb 18, 2021

Purchased my MF 1240 4 WD with manual transmission back in 1997, new. Great compact tractor and had no major problems until recently. Engine would not turn over! Checked battery and determined that starter might be the problem, replaced starter and ignition switch and problem continues. Not much of a mechanic but can follow wiring diagrams. Unfortunately, don't have a good WD and am specifically looking at locations and wiring for safety switches. Suspect that or safety relay.

Question 1: Where is the safety relay located on this tractor?

Question 2: Is there an easy way to bypass all the safety (interlock) switches? Appreciate any help.....thanks

I have a MF1250 compact, also having a problem....found a relay behind the right side inside dash and my problem is it will not turn off via the key, I have to remove the right side engine compartment cover and push in what I call the solenoid mounted midway top to bottom and front to rear. 2 wires. How do I know if it's the ign.switch, relay, or solenoid that is the problem?
