glad you sorted it but when did the fuses get removed? serviced lately or you raped them for something else?

not quite sure actually, theyve never been touched while ive had it but i didnt check voltage before or after i put the 25det in so it couldve been like that for aslong as ive had it

put fuses in places where it was missing fuses and the overcharging is now gone.

wow!

I've got the same problem in my stagea, 15.1-15.5v and have just changed the alternator for the same result.

so...same question for you that you had for Paul....which fuse(s) did you return/replace???

I'll double check all of mine as well!

Most of the fuses in my fuse box in the engine bay were gone, i had two headlight fuses missing (and for some reason my headlights workd) i had a aircon one missing i had removed the aircon when i put my motor in but there was still power going to that fuse. i was also missing a large main fuse type 30a fuse.

all of these were in the fuse box under the engine bay.

and there was only 1 10a missing in my in cabin fuses.

I was also asking around when this was all happening and i was asked if my speedo was working, which it isnt (getting it wired up when the auto sparky gets a chance) and they said that the speedo on a rb25det box will zap alot of power, so if it isnt connected its not there to take any of the voltage that the alternators putting out so it overcharges. Thats 2nd hand info tho so dont know how true it would be.

cheers for every1s help btw especially paul, good man

dont know sorry. the auto elec checked everything and bench tested the alternator and it was fine

he then put it back in the car and did some testing and eventually found a missing fuse in the boot, he replaced it and problem solved

he couldnt believe it either and was pretty surprised at the fix in the end given the fuse was in the boot

On quite a few of the newer alternators, the alternator warning lamp forms part of the regulator circuit. They will overcharge or not charge at all without it working.

Not sure how this circuit works but I have heard of VL's having similar problems.

    • So, I've been a little busy on this car. I replaced the bonnet struts which is always satisfying but very confusing that nobody else on the planet seems to do this. Its just my routine first thing I do on any car I buy. The boot struts for both the tailgate and the separately opening glass window was a bastard. And, I found a fair bit of rust in the strut cavity. I filled it with rust converter and cleaned up as much of the dirt as I could. There was so much dirt. One piece of the trim was barely hanging on and so I've left it off. I'll try to get a replacement. You can see how disgusting and dirty it all was in this thread; I had to remove the little clips that hold the struts on the ball. The ones I took off had no clips and it was impossible to get them on with them in place. Fingers crossed they stay put. So, I turned my attention to the headlights, they were in a bad way and likely would stop rego. I took the headlights out and found the adjusters were all just loose. So, I fixed those and unclipped the lenses to clean them up. Couldn't believe how easy it was to take all this apart compared to the E90.   I also cleaned up the stockies which was awesome, these are super cool with lug nut covers. They're in good nic but the tyres are shot. I was going to use these for rego but in the end got a fresh pair of rubber for the 17's on the front of the car instead. The front bar of this car is from a late(r) model one. I don't think it's quite LCI but who knows. I'll need to find out. Anyway, the bar was missing the fog lights and the wiring and plugs were for the original ones so I got new plugs and some cheap fogs. I wasn't sure if missing original equipment would hamper my blue slip attempts. Had a couple of these little fellas helping out. But not Ben who got stuck behind the pool heater .... How embarressment.  I ordered new speed sensors for all corners because I knew one was out. I just got cheapies and will replace them with Bosch items when I can find Bosch items. Again, this was just for rego. Alas, it seems the blue speed sensors are not the same as the grey ones. Back they went and replacements ordered. In the end, with my new scan tool, it was just rear left that was shot. Replaced it and cleared the codes. All good now. Lastly, my aux (thermo) fan is being a bit odd. Its powering up at strange times and NOT powering up when I think it should (100C). While this can be caused by a few things, the most likely (for me) is the ambient temp sensor. Given mine reads -40.0C regardless of the temp, I figured it would be good to replace it. In the end, the sensor wiring was abysmal with (terrible) attempts made by somebody to fix it.   I fixed this all up but the sensor is only attached using pins into the wires. The plug is not there. Despite trying and trying to connect it securely it wouldn't work so a replacement sensor and plug is on the way. Oh, I also ordered a replacement piece of trim for the part missing here at the bottom. Ordered from Latvia for $70 delivered. I took a bit of a leap of faith because I didn't have the exact part number and, as usual, there were eleventy billion pieces of trim that looked to fit. Nailed it. Well, its not totally perfect but I think its more a 28 y/o car problem than a trim problem. And, as of today ..... I have bought the workshop manuals 2nd hand off a guy in tassie. 1000+ pages of E39 goodness, hopefully it helps me with the fan. I also have a new temp switch on the way incase its the problem. Stoked.
    • I don't even know that you want an M2 Competition as a track car. My rule for a track car is only risk as much as you're willing to completely total out. Clean stock C5 Z06 Corvettes out here are cheap. Buying someone else's already ruined track car is even cheaper. Maybe I'm just not that good a driver but even a Fiesta ST on the Nordschleife felt like as much car as I could realistically handle.
    • I've already gone over the cam. A new one is going in. An old one is coming out! The new one is smaller, with less overlap. It has way more lift, but it will be more mild mannered (hopefully, probably very minorly) I'm also measuring for two more mufflers, with the goal of having four mufflers in my car. But that probably will be done by an exhaust shop in a drive in, measure, buy parts, install parts later kind of deal.
    • Mine is not even a GTR and I've been resisting the urge to make it a power monster for the last 25 years. And as a consequence, I have driven it to work nearly every day across that span of time.
    • Since the motor is out, I suggest pop in a nice dirty LS chop cam. MOAR of this please:
