nissan200sx.dk Posted November 2, 2012 Report Share Posted November 2, 2012 Hi all. I have a few questions about fuse size. (Amps) My setup is like this: (Each relay can handle up to 40 amps) 1 relay supply +12 volt to injectors. I have 10 amp fuse here. (6 x injectors) 1 relay supply +12 volt to ignition coils. I have 10 amp fuse here. (6 x coils) 1 relay supply +12 volt to ECU / sensors. I have 10 amp fuse here. (ECU, 4 x pressure sensors, 1 x boost solenoid, 1 x VCT solenoid, 1 x ISC solenoid, 1 x CAS sensor, 1 x TPS, 1 x MAP, 3 x relays for fans / fuel pump) Should i change my fuses to more or less amps? Thank you. Ronni Quote Link to comment Share on other sites More sharing options...
Simon Posted November 4, 2012 Report Share Posted November 4, 2012 I think the ignition coil one would need to be bigger as each coil will pull up to 8amps each but of course at any one time all 6 will not be on I would suggest a 30A Quote Link to comment Share on other sites More sharing options...
