[QUOTE="Haveacamper, post: 648414, member: 2051"] Hi All, I've just been setting up a bench tester and I'll be running a Carter electric fuel pump. I've wired up the double relay setup for the fuel pump as per D.Whipps's wiring instructions here: [URL]https://earlybay.com/threads/fuel-pump-relay-and-other-starting-issues.82142/post-644333[/URL] What I have noticed is that when connecting the alternator warning light to relay, the warning light no longer lights up when my ignition is on (15 live). Is this expected? FYI: I have tapped into the blue wire on the back of the warning light itself with a piggyback connector on the blue wire. I think the blub is no longer lit with ignition live because when connected to the relay, I have 12v both sides of the blub? Have I dont something wrong here? [/QUOTE]
