Alternator/starter Motor Issue

Recommended Posts

I have bought a r33 gtst

and it came with a problem starting it like a sticky solenoid and what i thought was belt squeal on startup

So i got the battery checked and charged fully

Changed the starter motor Problem solved.(Or so i thought it was)

Bout a month later the problem came back the sticky solenoid issue.

it was happening rarely once a week, but now its consistent with every startup

Also the alternator squeal has got worse witch on startup if it is screeching the Hicas light

turns on and i lose power steering and the lights dimmer.

Could the alternator be causing the starter motor issue making it feel like a sticky solenoid

as maybe the battery is not charged properly

It sits at 13v or so under no stress and seems to be keeping itself at that level?

anybody came across a issue like this

Cheers

Tommy

When you say the alternator is screeching, do you mean the altenator is screeching or the belt is squealing?

The only 2 noise related problems you can have with an altenator are belt loose/worn or the altenator bearings have gone or started to go.

Check the basics first because they are cheaper, a new belt (or tightening the belt) is alot cheaper then getting a new altenator

As for the starter clicking/sticking then this wont be an altenator issue unless the charge is down. If you have a turbo timer or Power FC Hand controller, set it up so you can see voltage all the time and check the voltage before starting and while starting. If there is low voltage on startup then you either have a stuffed battery or the altenator isnt charging. If the voltage drops from 12(ish) volts to below 8V (from memory) then you will have a battery problem.

Will do in the morning

Im pretty sure its the alternator bearings

my thoughts the alternator is not charging the battery back to full enough just keeping it low

If you have a multimeter then check the battery voltage when running with the multimeter in case there is any voltage drop in whatever you are reading the voltage off in the car because it does happen. It should be 14-14.5V, get a mate to rev the car while checking to see if it changes at higher revs to.

    • Agreed with the rest. Also at least based on my own research, there are no readily available stock or close-to-stock RB20Neo maps that you could download and use as a base were you to buy a complete standalone ECU, and the regular 20DET maps don't really work well so you'd need to take it to a tuner if you have no experience. I installed an AEM V2 on my 20Neo+T and had lots of headaches until I got it to run and idle properly but I've yet to remap it fully. You have to start building up your timing and fuel maps entirely from the ground up; even the ones for a 25 didn't work at all.
    • Got some decent progress after work yesterday and also today. Got the ECU all wired and passenger side interior all back together. Kept the wiring up nice and high to avoid people standing on it. Got the surge tank relays rewired and tidied up the pump wiring and cut a hole to bring the cables through.  I found a spare USB cable I had lying around so I decided to cut it up and see if I could use it for my CAN 1 bus. Turned out one of the pins I needed was to the shield of the cable so i cut it up and desoldered it and resoldered to the correct pins.  Had the issue with the powersteering hose hitting the A/C compressor and fan shroud. I pulled the bracket off and modified it to remove the front mounting point which now clears it all. Will keep an eye on it to see if theres any signs of fouling once it's up and running.
    • That's some good input mate. Nice.
    • So today I went well outside my comfort zone (again) to replace my valve cover gasket.  I have had a big leak over the exhaust leading to a lot of smoke and smell every time I drove it. The leak was in the rear driver's corner.  The job wasn't hard as such, just a bit finicky and time consuming.  The old gasket was rock hard and broken right where the leak was.  The leaky corner had so much sitting oil in it.  The good news to my amateur eyes was no buildup or sludge under the cover. It all looked fairly nice in there.   I haven't started it yet. I ran out of light and body when putting the coils and injector loom back in. Probs only 30min left for the morning.  I was so nervous putting the cover back on, I must have lifted it 5 times to make sure the gasket was still seated properly. God it's going to be nice to be leak free and not make other traffic light queuers think my car is about to explode.
