R3DG3CKO ROB Posted April 21, 2013 Share Posted April 21, 2013 (edited) Just been trying to wire in my rear fog lights and all of a sudden the stereo didn't work and now the car won't turn over? I think I tried it first thing this morning and worked fine (starting to doubt myself now). Was checking the lights to see if Heckler's PCB's are wired in correctly and noticed that the black wire attached directly to the ignition, going into the switch wasn't completely connected, so reconnected that and that was when i noticed the problem. The wiring has been like hat for ages, I changed the fog light switch last week but it wasn't wired in until yesterday with the PCB's Any ideas what to check? Starter motor is turning over but not catching. Edited April 21, 2013 by R3DG3CKO ROB (see edit history) Quote Link to comment Share on other sites More sharing options...
Josh42 Posted April 21, 2013 Share Posted April 21, 2013 Check the fuses in the drivers side footwell mate.... Quote Link to comment Share on other sites More sharing options...
safcdixon Posted April 21, 2013 Share Posted April 21, 2013 Have you checked the fuses? Quote Link to comment Share on other sites More sharing options...
Pudsey Posted April 21, 2013 Share Posted April 21, 2013 I would insulate those spade connectors with some insulating tape, so they can't touch at all behind the dash. As for your starting problem. I assume you have checked all the fuses? Quote Link to comment Share on other sites More sharing options...
R3DG3CKO ROB Posted April 21, 2013 Author Share Posted April 21, 2013 Checked the drivers side, there's a 7.5A fuse gone - RAD No 2? Quote Link to comment Share on other sites More sharing options...
R3DG3CKO ROB Posted April 21, 2013 Author Share Posted April 21, 2013 (edited) Changed that with a spare from the main fuse box but hasn't done anything. Not even turning over now?

safcdixon Posted April 21, 2013 Share Posted April 21, 2013 Have you checked the main fuses in the engine bay? Quote Link to comment Share on other sites More sharing options...
R3DG3CKO ROB Posted April 21, 2013 Author Share Posted April 21, 2013 Yeah, all looks fine. This really happened just after I wired in the second (passenger side) PCB. I've unwired everything I've done including the cigarette lighter wiring but still nothing - although if the starter motor isn't turning, wouldn't that suggest that the battery has gone flat/shorted out? Only thing I haven't done is reconnect the brake light wires which were joined by the PCB Quote Link to comment Share on other sites More sharing options...
Pulley Posted April 21, 2013 Share Posted April 21, 2013 The starter motor turning but not engaging sounds like flat battery, or perhapse weak earth, poor connection from battery Quote Link to comment Share on other sites More sharing options...
Guest 2JZ GE W58 Posted April 21, 2013 Share Posted April 21, 2013 +1 on insulating them spades, they look like they'll touch easily causing a short and bust fuses Quote Link to comment Share on other sites More sharing options...
R3DG3CKO ROB Posted April 21, 2013 Author Share Posted April 21, 2013 Checked the battery and it's still showing about 13v - wipers/windows/headlights still work = baffled and frustrated Yeah going to insulate the switch connectors but none of that's wired up at the moment Quote Link to comment Share on other sites More sharing options...
Guest Chris Green Posted April 21, 2013 Share Posted April 21, 2013 When you turn on just the ignition does the battery light show up Quote Link to comment Share on other sites More sharing options...
safcdixon Posted April 21, 2013 Share Posted April 21, 2013 Dont know if its possible but could you have damaged the ecu somehow? Have you checked too see if youve knocked a connecter whilst messing with these wires? Check everything pushed home correctly etc Quote Link to comment Share on other sites More sharing options...
Pudsey Posted April 21, 2013 Share Posted April 21, 2013 Is there a glass fuse in the driverside footwell on your car. It will be a in line fuse that screws together to make the circuit, contained in a black tube. If you have one and its blown that will stop the car from starting. Nb. Bad earth as pully suggested would be the next port of call, along with a battery check as Supra s really need a good strong power feed.

Guest Chris Green Posted April 21, 2013 Share Posted April 21, 2013 If you think the starter isn't engaging properly it might be worth testing it before you spend hours searching for a wiring issue - - - Updated - - - If you think the starter isn't engaging properly it might be worth testing it before you spend hours searching for a wiring issue Quote Link to comment Share on other sites More sharing options...
R3DG3CKO ROB Posted April 22, 2013 Author Share Posted April 22, 2013 I'll check the Black fuse when I get home from work and make sure I've not knocked any wires out too - It was definitely something to do with the way I wired up the rear lights as the stereo died exactly when I turned the lights on at the stalk. After that the car tried to turn over without any joy. Worst part of this is that my fiance is flying in from the US on Friday and the whole point of getting all this stuff sorted was so the car is up to scratch and reliable lol looks like I might have to get a hire car at this rate Quote Link to comment Share on other sites More sharing options...
R3DG3CKO ROB Posted April 22, 2013 Author Share Posted April 22, 2013 OK, how do I take the black fuse out? I've tried looking at the ones in the main fuse box to see if that'd give me a clue but can't see any pinch points or clips etc. do they just pull out?

You will find a glass fuse inside. Quote Link to comment Share on other sites More sharing options...

Doesn't feel like it'll unscrew without me tearing it from the box lol You can see the ones I mean in the pic below, my battery is way too low to use the flash in the footwell but you can see the type I'm talking about.

safcdixon Posted April 22, 2013 Share Posted April 22, 2013 Those black one above just look like relays too me mate, the ones too check are the one with the see through covers in the top corner of your pic Quote Link to comment Share on other sites More sharing options...
R3DG3CKO ROB Posted April 22, 2013 Author Share Posted April 22, 2013 got both of those out - they have a greeny tinge to them but appear to look intact? Quote Link to comment Share on other sites More sharing options...
safcdixon Posted April 22, 2013 Share Posted April 22, 2013 There should be a 70a one too if that's intact too I don't know what to suggest, do you have a multimetre? too check you have voltage going to the starter etc Quote Link to comment Share on other sites More sharing options...
R3DG3CKO ROB Posted April 22, 2013 Author Share Posted April 22, 2013 I'm waiting for my mate to get here and try jumping it, as I think it's just the way I had the switch wired up that's caused the battery to drain (fingers crossed) but yes I have a multimeter so that'll be the next thing to try I guess Quote Link to comment Share on other sites More sharing options...
Pudsey Posted April 22, 2013 Share Posted April 22, 2013 Ah no, that's the relays. In the drivers footwell to the right, next to where your foot would be on the throttle, you may find a in line fuse behind the panel. Its about an inch long with one wire in, and the same wire out the other end. It contains a glass sealed fuse. I know this stopped a car starting in the past.

R3DG3CKO ROB Posted April 22, 2013 Author Share Posted April 22, 2013 All sorted. The battery had just died die to my poor wiring on the switch :-( Quote Link to comment Share on other sites More sharing options...
