MF 1155 1973 relay question

[camocorvette]

Hello,

New here, used this forum a few times over the years to find info.

My cousin has a 1155 with no power coming out of the relay in the cab. This relay goes to the 25 amp circuit breaker that goes to the blower switch/blower.

Where can I find a replacement for this?

It's the relay above the cab.

Or will any relay work? Thanks in advance
Will

I'd use a CONTINUOS duty solenoid, similar to a starter solenoid to replace what you have. MAYBE you could remove the cover and clean the contacts and get what you have now working again? I've done that a few times on some old voltage regulators. Worth a try, you can't hurt it if it is bad anyway.

Welcome to the forums.

At a parts store you should be able to get a 30 amp (they are available in various amperage ratings) plug in type relay as they currently use in autos and a base for it. It will have wiring info with it, you will not need to use all the terminals on it but will need to add a ground wire which your current relay doesn't have. You want to wire it as normally open, so it closes (powers the breaker) when the switch is turned on.

Should be part number 530178m91. Google the number, maybe there are some out there

Thanks a bunch! I will pursue these leads and post up what works. Gonna take it apart and clean it and look up that part number and see if I can find one. Otherwise I will hit up autozone.
Again, thanks for the help. I greatly appreciate it
