Help! Electrical Problems

[xmafia]

Iv just got me a 1990 skyline coupe, factory rb25de manual and as i was driving it home i lost all my dash lights, tail lights, brake lights, rev gauge stopped working, electric windows... pretty much everything but the front headlight, car would still start but hard to run, i did purchase with a broken off airflow plug so wasnt revving out past about 2600-2750 revs but still was drivable until i lost everything else.

It may have had a new ignition put in it as key dosent work on the doors, unsure tho as im having difficulty getting info out of the previous owner.

Any ideas? and where should i start? with the battery leads? ignition? checked fuses, they are all good.

Thanks in advance!

Check all fuses. But if they are popped u need to work out why.

Its possible ur alternator is overcharging

None off the fuses are broken

Did you check the links on the +ve terminal on the battery?

Figure out the problem.

The previous owner had hard wired the main fuse and it had disconnected, cant believe i didnt pick it up before.

thanks for the help tho.
