room fuse blows

hey all


give yous a run down what i have been doing


1993 626 gv wagon with 88 626 turbo gd wireing loom the full kit


so a few weeks back before i put the turbo engine in i was having trouble getting the blower motor fan to work but i got that working

so i hooked the rest of the loom up and put the ecu in and when i go to turn the ignition on the room fuse keeps blowing so i pulled pretty much everything back apart and couldent find no fault

but i do rember swapping the 2 relays next to the batter over trying to get the blower motor to work and i used the 2 relays from the gv wireing loom

anyways i completely forgot about the relays and i went to hook the battery up and thats when the room fuse kept blowing

does anyone have any info on these 2 relays next to the battery

this only started when i put the engine in and put the rest of the interior bits back togeather like glove box and steering shroud and center console

other then that the engine cranks fine i can hear the fuel pump head lights and turn signals work fine brake lights work fine

but what doesent work

cd player
ciggy lighter
interior lights
door lights

so to try and find the fault i disconnected the followings

engine loom to dash loom

alternator,starter motor to battery

disconnected the cd player

disconnected the interior lights

still keeps blowings

Just for shits and giggles disconnect the blower motor and try it again.

I'm betting it has something to do with mismatched relays.
There are a few circuits (radiator fan for example) that changed form N/O to N/C or vice versa.

And then there are all the different trim levels that the cars could be optioned with (climate control for example)

What you need to do is go through every load, relay, resistor pack, etc, that is connected to the fuse that is blowing until you find the one that that is drawing the current. Then test the item against what the WSM says it should be.

This whole debacle could have been avoided by using the tried and tested methods used by Sabbai and Jessiotrot when swapping their wagons to turbo.

im betting that its the relays too

because i don't even have to have the accessory or the ignition on for it to blow

If a fuse keeps blowing, it usually means something is amiss in the circuit. The wiring should be checked along with the components in the circuit to determine if there's a short or other problem.
