So I was about to do some work on wiring with my starter when I accidentally touched one of my wires to the ignition coil next to the battery. A couple sparks came out and then I realized that I forgot to take out the battery before this and now my car has no power. there’s no interior lights...

Hello, I'm very new to working on cars and have been working on a 1987 supra, which is also my first car. This yellow box has been giving me a lot of trouble, but at this point, I'm sure it's due to the slightly bent connecter I circled below which only works when it's pulled back and angled a...

Help!!! My headlights are suddenly not working and I don't know why. The rear lights, parking lights, turn signals and fog lights work. Before, both low and high beams came on if I held the lever towards me, but in the normal position the low beams did not turn on. As soon as I pulled the lever...

I let my car sit for a couple days (4 days) came back and the thing was dead. I've had this happen about 4 times already and I have gone through 2 batteries already. I have a brand new alternator (140 amp 7M Alternator) and wiring. Ive also never had it die on me while driving. Has anyone had...

Was able to get my car to get power to everything but now the starter wont go and crank the car. I put a multimeter on the power plug for the starter to make sure it was devliering power and it read 10 volts. When I turn the key I can hear clicking from the right side of the car (maybe the...

Recently have put my engine back into my 1989 Supra and am trying to get it to start. Issue is there is no power anywhere. The battery is connected and everything that needs to be connected to make it work is. The gauge cluster doesn’t light up when I turn the key and the starter doesn’t go. Not...

Hi all, new member, first post on here. I recently traded for an 86.5 supra with the 7mge motor in it, guy before me took the motor out and refurbished it. After the refurbish he couldn't get it running due to a suspected goof in the fuel system. It also sat in a garage for 12 years. I...

Hi. So i have been having a problem with the Master warning light and the Hand break light staying on even if the hand break goes down,they just slightly dim but that is all.

I have a 1987 non-turbo 5-speed (converted from automatic). I recently had my voltage regulator go out with a bang. The 1.25B ALT fuse was completely fried. I’m pretty sure the regulator developed an internal short that basically connected the alternator output and battery positive to ground. I...

I was hoping some of you Supra gurus could help me out a little. For some background, my Supra is a stock 1989 turbo to my knowledge and hit what I can only assume was fuel cut around 5k rpm in 3rd. It felt like the engine cut off, acceleration stopped and the CEL came on for a few seconds...

Hey all, so I bought this car in October of 2020, I’m currently redoing the battery terminals and can’t seem to figure out if I splice this cable into the negative or positive cable. Somethings telling me it’s to the positive but electrical makes me second guess myself

So, my 87 mk3 turbo manual has been having weird electrical problems since the head gasket replacement... the car will idle correctly for a very long time but eventually shut off (no bogginess or gauge fluctuations just dies even though alternator works, new battery etc.) also the car winks now...

Hello All, Again I'm posting because my broken Supra seems to still be causing problems. So she has a very werid start pattern and sometimes just decided not to start, even though the battery, alternator, and starter (new) all check out. Now just today I started the car and it started...
