In other words I have got 4 relays for the fans, all of which are connected to a 70AMP MAXI FUSE.
Is it OK to have a common MAXI FUSE for the 4 fan relays? I am not a wiring guy, so not sure about this set up.  |
I am not sure why you have 4 fan relays? A Spal wiring harness has 2 fused relays that connect to a battery source ( yellow wire one for each fan). 2 orange wires that connect to 12v ignition, 2 grey wires that connect to PCM or temp sender. You can have several relays on one maxi fuse because the relay carries the load. (
