OK i bought a 1993 civic si with an engine swap for a b18b, my problem is in the place of the 10A fuse in the intstrument,taillights spot some idiot put a 25A fuse in now when i put the 10A fuse in still no lights or cluster so what can i do?.

Secondly my moon roof opens sluggishly and sometimes the motor will be running fullspeed but the roof wont move whatsover is it because it is cold here (usually around -20,-30) or do i have a serious problem

 

A.why the expletive are you opening moonroof when its that cold. but on a serous note it might just be because of the cold i noticed mine does go a tad slower to on extreme cold days.B. on the wiring check wires and **** like that is my only guess get a voltage meter or watever ther called and make them things ur friend basically.

 

i hate to say it but prepare for the worst, im not sayin this is the prob but its most likely to happen.........the wires in that circuit can only handle 10amps or less, thus the reason for the 10 amp fuse, when the amperage in that circuit exceeds 10 amps, the fuse blows, right? now, putting a 25 in there allows for a maximum of 25 amps to flow through the circuit, but the wires can only handle 10, i think the wires in that circuit are burnt out.

as the comment b4 mine....u need a multimeter and a test light to test the circuit, if the wires do not conduct any electricity, or the resistance is to high, your wires are bad and need replaced.......

 

I was opening the moon roof cause i just bought the car and wanted to make sure everything worked

 

**** i hope its not that problem according to the owner of the car the rear ballast isnt in so i gotta replace that first, the car has been stored so i hope nothing is burnt out
