Re: Probs with fuel pump & RPM relay

[knut.s.grimsrud@xxxx]

There is no "priming" that the RPM relay does. The relay has a 
delayed shutoff of about 2-3 seconds, but it does not "prime" for a 
couple seconds first.

The relay is activated upon the first impulse it detects from the RPM 
sense, and it shuts off 2-3 seconds after the last impulse it 
detects. For the fuel pump relay (also known as the RPM relay) to 
activate, it first needs an impulse from the RPM sense. Once 
activated it will stay activated until 2-3 seconds after the last 
impulse it receives.
