Hooked Battery Up Backwards C33 Rb25Det

[25plusturbo]

hi there did a retarded thing and hooked battery up wrong way fryed my ecu and turbo timer have replaced both of them and the fuses the car runs now but it has few problems.

have lost power to rev gauge headunit and windows

there is a round black relay that clicks every 10 seconds and the power drops fuel pumps quitens and dash lights dim

tryed replacing not 100% sure on 1 i put in but it clicks aswel

any 1 have any idea what would be wrong cheers

check for burnt out ground points as well

You could have ruined all the wiring in the car. The casing on the wires may be melted. Anything electronic would have been prone to serious damage dude.

ok so i found a melted ground from where turbo timer was grounded have replaced that didnt solve anything,

video of running

have been told could be blown regulator in alternator cauing overcharge im going to test what the battery is putting out tonight

i just cant under stand how everything runs fine like temp gauge and heater indicators head lights etc but just windows and rev gauge wont work and the clicking relay and possibly headunit going to replace fuse in back of it and plug it back in.

hopfully try putting new alternator on aswel otherwise i think ill have to take to sparky

also i tested the battery and my results were 12.3 when 1st hooked up battery from my 07 hilux when relay clicks 11.9 , car runnin 14.3 clicks 13.9 after turned off 12.7 clicks to 12.3 havent tested from alternator but from what i seen from battery it isnt over charging, was just wierd that i couldnt jump start it i had to put battery from truck into laurel and started mint

[Dan_J]

will unplug it and see what happens on the ceffy

after u jump start it remove jumpers from hillux.if alt is working it should be at 13.+ volts 13.6/13.9 etc

using same battery that u put the wrong terminals on?

could have blown one of the cells inside, i have had a case where a bat was showing 12v+ and not starting only to find battery was gone, fixed with a new bat

[25plusturbo]

if i unplug it it runs fine and doesnt click but something must be wrong with the rev gauge and windows must be a ground somewhere tripping it.

when i tryed jump starting i had batt in that got hooked up bakwards it had dash lights n everything but like died when i went to turn it over even when leads hooked up. i will try replace the alternator tonight just to see if it fixes anything

[25plusturbo]

okay so i pulled apart the dash loom and followed the clicking relay wire and it went to the window amp in the passenger door must of fryed it aswell, unplugged it and clicking stopped, windows started working again except passenger havent been able to check rev gauge as manifolds off getting planed but im guessing it will be working
