Hi, I plan to install two new fuel pumps to my car, while keeping the original in place as well. Forg provided a bit of help IN THIS THREAD HERE , but I'm just chasing perhaps a different alternative to consider.
A standard relay would normally have the following, right? Well, thats what mine has anyway.
(a)12v input from battery
(c)output to pump
(d)output to something else, ie, std pump (?)
This is what Forg said :
An easy way to wire up what you've got would be to run a relay's trigger circuit off the power supply to the pump you've already got mounted, and run the power for the second pump through the relay (and a fuse).
From my understanding, that would install a new relay, with the output to pump (c) from the first relay becoming the input (a) for the second relay? correct?
What I was wondering, is it possible to get a relay which can supply power to three different pumps to get rid of the first relay??
output to pump 1
output to pump 2
output to pump 3
I'm worried about voltage drop affecting the operation of the pumps.
