1G ABS light randomly turning on and all accesories failing

[Skreperiukas]

Hello people of the internet!
So a couple months ago I replaced my alternator and made a heat shield for it. Whilst changing it i found that there were power steering pressure switch, oil pressure gauge unit and oil pressure switch for the low pressure oil light connectors that have been disconected for God knows how long. After all of these fixes I begun to experience a new problem. Once in a while when I start the car ABS light is on and all electric accessories dont work. I do have volt readings and they are as supposed to be 13.6-14.4V. What could be the issue? I tried searching for similar threads but couldnt find anything noteworthy.

Suggest trying disconnecting the power steering pressure switch, oil pressure gauge unit and oil pressure switch as a test to see if problem goes away. If so it points to something improper you did with your "fixes".

Ok, I will, but how does disconnecting old alternator and connecting new one can be done inproperly? Its just one pin

Ok I thought you were referring to those 3 separate sensors (like the 2g has). But if you're talking about the harness you "fixed" that goes to those sensors, I'm just suggesting you try unplugging it to see effect (ie. if electric accessories then work).

Maybe. I dont have a good memory but I think I had this problem once or twice before changing alternator. I did change my clutch a year ago, could I have knocked one some sersor that does something? I did have to remove ABS system to remove a few bolts holding tranny. And this whole thing is weird because this abs light phenomena happens once every 6 or so startups and after 10minute drive everything starts working as it should

Ya then I don't know. Some ideas: All fuses are good? Large battery cables terminals/posts clean and tight? And alt is always charging battery when electrical accessories on or off? Battery cable or alt to battery wire have intermittent internal crack where vibration makes it work/not work? With everything starting to work after 10 minutes you may have a bad connection or bad wire. When things are all working, you might try wiggling all wires and connectors to see effect (if there is a bad connection/wire).

Ok I will try that this weekend when i go to my grandparents, as I am going there to remove old cracked hood paint and prime ir before wrap. I live in a city and dont have access to a garage with pit. Thanks

Hey man sounds like you have a failing alternator

I know it sounds like that, but I just literally changed it and made a heatshield. After long drives I tested the temps and it was cool compared to when I didnt have heatshield. I refuse to beleave that it could have cooked for the THIRD time since I got the car.
Also as stated above, voltage is right. The alternators that have been cooked before didnt charge so it doesnt make sense. I dont drive this car much.
Edit: i will add that radio works fine, which never worked when alternators were bad
