Voltage issues.... Keep blowing fuses to nitrous system

specvfrog · 2008-07-28 13:33:05

I have been running my nitrous setup for about a year now off a 30 A fuse with no issues. Yesterday I blew that fuse at the track for the first time. Thereafter, I replaced the fuse several times with 30A then I switched to 40A(which is the highest A that seems to fit). Every single time I put a fuse in it would blow either the second the nitrous kicks in or after a couple of gears.

So basically, I am thinking I need to install a new fuse system that will handle more voltage. Just curious what you guys use or recommend or if you believe that something else could be wrong with my nitrous system.

Check your wiring for a short, mine did that and I found a wire had rubbed on a sharp point and finally went through the insulation on the wire.

You got a short somewhere.

Please check for a short.

FYI, fuses work off of current not voltage. Even thought voltage is a function of current. Also, you should never exceed the circuit's amperage rating by simply putting a bigger fuse in place. If a fuse blows on a recommended amperage then you obviously have an issue that needs looked into. Putting a higher amperage rated fuse in will just cause more problems.

thinking wrong, first the fuse is most likely blowing up due to a short causing to much current flowing not voltage. Visual inspect your setup for wires touching stuff or other wires. check all electrical equipment out too, if the fused was desgined to work with it like it did then you do not up it to a high rated one becaue it blew, it did its job correctly.

Thanks for the info guys.

I did a visual inspection when it happened and couldn't find anything abnormal with my wiring in plain sight. However, as you guys have noticed, I am definitely no electrical expert so I will have someone check it out.

did you get this figured out? look at your splices and grounds, sounds like a bad connection or a short somewhere.

are you running a relay after the power switch? if you're not this could be your problem.
