03 SVT gauge flicker/sweep

I have been dealing with this issue for about a week now. On Monday it started flickering the abs/traction control/brake/CEL and the gauges started to sweep. I went to advanced and got my alt checked and it said "ripple" which means fluctuation of voltage.

After doing some research I checked the number 10 ignition fuse and it was a bit burnt but not broken so I changed at and the grey wire on the alt plug pigtail was exposed so I bought a new pigtail and replaced that.

At the same time I checked and cleaned all grounds and battery terminals with a wire brush.

It didn't fix the problem. Is it time for a new alt? I have been trying to avoid this because I just spent 250 bucks for a new starter but whatever.

"""and it said "ripple" which means fluctuation of voltage. """

Check it yourself. Get a cheap voltmeter, set the volt meter to AC VOLTS. Measure across the battery while the car is running. If you see any AC Volts then the diodes inside the alternator have failed. Also check a good car same way

Do you have a harbor Freight in your town? They have the cheapest voltmeters

I tested the car at idle and with some gas and it doesn't show any AC volts. I'm gonna go drive the car and try to get it to flicker then test it to see if its showing AC then.

As he says, ripple means at least one diode has let go. Check idle running volts at battery, should be 14+, if only 13.6 or less then more proof of bad diode.

I've fixed that by simply resoldering the diode end if no other damage there. That was several years ago and alt still runs fine.

Ok i tested that and it was a constant 13.6 volts at idle. So if i removed the alt how do u fix the diode?

I drove it for 40 miles round trip today with no problems. Seems to be very random.

I haven't had a single problem since I took the battery cover off. Maybe it was pushing on some wires?

If it is then you didn't tighten them.

Alt must disassemble to fix diode and test parts. If diode tests bad then new alt. Problem is, you can't test diodes without desoldering ALL of them to isolate. You have to figure out which one of 6 or 8 is bad too.

At 13.6 volt you can drive 2-3 weeks before battery spits out.
