[DML] Re: RMP Relay woes?

["bitsyncmater" <david.mckeen@xxxxxxxxxxxx>]

Your fuel pump fuse is #7.  Fuse #1 powers lots of things providing "KEY ON" power.  RPM relays do often fail intermittently because of broken solder joints.  The OEM RPM relays get very hot and have single sided PCB boards which leads to broken solder joints.  You should carry a jumper to "jump the RPM relay" so the next time it happens you will know what fails and save you from getting towed home.

What exactly does the RPM relay do, and does it rest itself when it cools after about 10 mins of sitting, will this relay also take out the fuel pump briefly? or is there a circuit breaker that is giving me a hint that it is heading for the trash?
