Starter - Glow Plug Switches

I'm starting to get some intermittent starting problems from my engine (MP25) and based on my electrical knowledge and searching on this site, have traced it down to the switches.

Does anyone have the replacement part numbers so I can go ahead and order them?

Thanks,

Wiring

I made the change-over to the heavier solenoid wiring recommended herein, and it made a huge difference.

Thanks to all.
I just ordered 2 of these switches from Defender.

You might want to first just check the connections on the existing switches. I looked at those connections on my panel last weekend when I replaced the oil pressure alarm and the screws were a little loose and the wire terminals were had a lot of corrosion on them. Sometimes the engine wouldn't turn over when the starter button was pushed. I thought it was an intermittent problem with the switch, but it might have been the loose/corroded wiring connections. I replaced all the wire terminals that connect to those switches, hooked it all back up and it seems to have made a difference. We'll see after a couple more startups if I have any more issues.

It may not be the switch. There was a bulletin out by Universal that the wire from the solenoid to the switch was too small and to install a larger wire.
