where is the 100amp fusible link? and battery terminals attached wrong

[washerman]

Hi,
My buddy connected my battery wrong on my 240sx and now the electronics on the inside of the car dont work ( wipers, speedo, pop up headlights...)

1989 240sx with sr20det , the car runs still but no electrical components work.
I also have a relocated battery to the trunk if that helps.


1-I was doing some research and it said my 100amp fusible link could have blown but i can't seem to locate it,
Or would that even be my problem? not sure where to start to fix all this.

2-Or could it be my ECU was fried i also read that somewhere

Thanks

- i found the 75amp alternator fuse blown, not sure if replacing this will fix the problem

there is no 100, the fuse u need is the 75 that u listed above. go to the junkyard and find one, u cant get them from anywhere except junkyard or nissan dealership. that will fix ur issues.

the car may run, but the alternator isnt charging the battery with the fuse blown so it'll kill the battery

will thhis fix all the electronics not working inside?

the speedo, wipers, pop up headlights and such

i got one ordered. and it should be coming in soon.

Without that fuse you pretty much have power to nothing.

everything is fixed and working now

thanks everyone!
