Caesard Posted May 25, 2013 Share Posted May 25, 2013 Hi all, after my engine swap, i am having a couple of electrical problems. The first is that when i am driving, the lights on the dashboard with the oil cans on the right and the other lights on the left flickers on and off. When it does that, the engine tone changes and the car behaves as if it wants to stall, and sometimes actually stalls. Then when i stop the car and take the key out of the ignition, all the lights on the dashboard and all electrics still stay on until i open the driver 's door. That shouldn't be happening, so i will appreciate any help as i am not too clued up on electrics on the supra. Also the odometer lighting is too faint to read and becomes virtually impossible to see when i turn the headlights on. Quote Link to comment Share on other sites More sharing options...
Scooter Posted May 25, 2013 Share Posted May 25, 2013 Assuming it was 'just' an engine change and none of the dash lights were messed with then from what I've read on here in the past I'd suspect an earthing issue..... Quote Link to comment Share on other sites More sharing options...
Caesard Posted June 3, 2013 Author Share Posted June 3, 2013 Okay, update: Found the battery itself was not earthed, so I earthed that and my power steering started working. My battery terminal has one of those gizmos that displays battery voltage and mine is between 12 and 13 volts fluctuating. But the car now stalls once i am stationery and the flickering lights on the dashboard is still happening. Please help. Quote Link to comment Share on other sites More sharing options...
Noz Posted June 3, 2013 Share Posted June 3, 2013 Perhaps wire in a new earth. The supra manuals should give you indication to which output number wire the earth goes to. Or you can just buzz this out with a multimetre. Wire in a new earth from the dash to perhaps the radio earth. That's one typical problem/cause that's striked off the list or solved your problem.

Caesard Posted June 3, 2013 Author Share Posted June 3, 2013 Okay, will try that. Will it probably fix the car stalling? As i have put in new spark plugs, brand new coil pack connectors and a new battery. Am bpu by the way. Quote Link to comment Share on other sites More sharing options...
Noz Posted June 3, 2013 Share Posted June 3, 2013 I doubt fixing an earth issue on the dash will solve the problem of it not running correctly. If the dash is in conjunction with the engine not running correctly, I would ignore the dash problem and resolve the engine, as they are problems linked together if it is an electrical fault. perhaps look into what was changed/modified/disturbed during any BPU upgrades. May help direct you to the problem Quote Link to comment Share on other sites More sharing options...
