Default Re: How to Repair Relay Control Module (RCM) - (Mystery no Start)

Nothing obviously wrong here and all soldered joints look good and shiny, no sign or a dry joint. None the less I went through and re-soldered as suggested.

Refitted the module but no change!

removed the module again and checked all relays do work and buzzed out the open and closed contacts were as expected!

Any ideas guys? I'm at a loss as to what to look at next?

You say the battery is fine - have you had it checked or is it just fully charged?

Also - with the fan running at high speed, I think that is an indication that one of the relays has failed, can't remember which one.
