What do the two fuses on the relay/regulator board in the engine compartment protect? I thought one was for the heated rear window (which I don't have but there are two 25 amp fuses) and one for the fuel pump. When I operate my heater fan I blow the fuel pump fuse. Does the same fuse protect the pump and the fan, or is the heater circuit somehow shorting to the fuel pump circuit?

Does the same fuse protect the pump and the fan, or is the heater circuit somehow shorting to the fuel pump circuit? the first fuse (the one towards the front of the car) is 8amp. according to my wire-diagram, it does not seem to be used ... the second fuse (the one towards the rear of the car) is 25amp. it is for: 1) Rear Window Heater relay 2) Gasoline Pump Relay 3) Heater Blower Relay where 1) is the relay right below the fuse, then comes the relay for the Power Supply, then 2) the relay for the gasoline pump, then 3) the relay for the heater blower the right cable for the heater blower comes off pin 11 on the second connector plug (the one towards the rear of the car). it is supposed to be a green wire. 1 - 2 3 - 4 5 - 6 7 - 9 - 10 11 - 12 1 = green/red = oil pressure switch 2 = gray/brown = ??? 3 = green/black = oil temperatur indicator 4 = gray/brown = ??? 5 = black/pink = ignition coil 6 = yellow = starter 7 = black/red = ignition coil 8 9 = ??? (connected to fuse 1, 8amp) 10 = ??? (connected to sportomatic) 11 = green = heater blower 12 = white = supplementary air valve hope that helps, Andy (IMG:style_emoticons/default/aktion035.gif) |
