Yanmar Start Switch

Recommended Posts

Yanmar 3gm. Press start button- nothing happens until, after random presses, I get a

connection. I seem to remember reading about this a few years ago, but I have lost the reference.

Something to do with replacing a small gauge wire from the start button to the solenoid?

Anyone enlighten me with a fix please?

Emergency, screw driver short large terminals on solenoid. If that doesn't work faulty solenoid. Also check all junctions bac to ignition key switch, unplug replug several times, undo and clean red wire to ignition key switch terminal. Same with start button. Check engine ground.
When you have time run bigger tinned cable or install relay.
Plenty on youtube.
Yanmar start circuit wire and wiring sucks.
