Got a problem!!!

I had my car dyno'd last night and as soon as it came off I noticed the battery warning light is on and the car seems to be charging the battery now at 16v, even on idle?? - I had a look today and there is fresh corrosion all over the positive terminal. Has anyone had this problem before or know what it might be?

As above.

Sounds like your alternator is overcharging the battery, this will greatly shorten the life of the battery and at worse case may cause it to leak.  Get the voltage regulator/alternator checked by an auto elec.

cool, Im going to take it somewhere tomorrow and get them to check it out - Im not sure but it looks as if the seals on the screw tops on one of the cores is maybe busted out...... :)

do you guys have any idea on what that would cost to fix by any chance??

The Battery light is an indicator for the altenator only, it does not come on if the battery is stuffed.

The light excites the alt, and if it is not regulating the reg must have given up the ghost.. If you remove it it will be cheaper for you, just tell the auto elec that she is charging at 16volts and let him go from there. Nothing is worse then someone bringing in a alt/starter and saying "this dont work" without acctually seeing what its doing.

Saying that the reg is stuffed might also be incorrect as most alts have a voltage sensing wire, and it has blown a fuse or has a break in the wire, the alt will detect no battery voltage and therefore charge flat out.

ouch, that sounds a bit pricey.

But I would dare say the labour component in sydney would be far dearer then out here.

Damage?? what kind of damage is he looking for? only time damage occurs is if the stator burns out or a bearing collapses.

Hey guys!! It ended up being fixed - if i had more time I would have shopped around for the price but needed it fixed quickly..

The guy ended up replacing the bearing and the regulator (looks really wierd? has a heatsink on it and a round circle area? looked like the bearing sat in there) - it ended up costing $269 all up. The guy seemed to know what he was doing, and its working fine. Crisis over!!! hehe

Most autoelec's do... LOL

Its always good practice to do bearings when servicing an alt... Shop policy here otherwise we will sell the reg and you do it. The labour on an r34 would have been the reason for the $200 part of the job. Ripping an alt down and working on it will take $50 worth of parts and about 20 minutes if nothing too serious. Its the pulling this off to get to that and then putting it all back together which is where most of your money went. But $269 is good....

hehe I guess you'd definitely hope so!!!!!!

the price for the reg was put down at $90 and the bearing was $35. The rest of it was put to labour, he said there'd be about 2 hrs of work in it (maybe also the fact that he didnt really know what car it was!!!! hehe he was an old bloke)

    • Initially I thought having a pair of Recaro seats would be a big bonus, it turns out these do get a little uncomfortable on long journeys (my fault, not the seat). I had a look through the GSM Performance website at reclining seats and booked an appointment to visit their show room. I got the Recaro Sportster CS for the R34 from here, was very happy with the service received so of course a re-visit was in order. Unfortunately the two Corbeau seats I had chosen aren't on display but they had 4 other options available. Two seats dug into my back, one dug into my legs and the other was perfect. I also found out that Recaro seats use a larger bolt pattern so some adaption was required. Luckily GSM offer some universal adaptors that should solve this problem. I searched the interwebs for price comparisons and Corbeau themselves were the cheapest at £300 cheaper (for the pair). I asked GSM if they could price match, unfortunately they couldn't. I later received an email saying Corbeau would honour them the same discount, but the purchase was already made. I did however order the brackets from GSM, both arrived on the same day. I started with the passenger side seat, knowing this was going to be a little trial and error. There are 3 mounting holes at the front and 2 at the rear on these JURAN Racing seat rails.  With the adaptor brackets mounted, the allen cap bolts started to push into the seat, NOT GOOD!  The rear mounting holes lined up but there were issues at the front. The holes were 1/2 hole out, so the brackets got a tickle with the drill to modify the holes. The supplied bolts weren't going to be long enough and a spacer was needed to stop the adaptor bars from bending. A local fasteners company supplied be with some nylon spacers and longer bolts (M8x30, although these will be replaced with 35mm long shortly) A before and after I pre-drilled the front bracket before making a start on the driver's seat to save some time. And in no time at all that was in the car too. The all black seats have transformed the interior and these are MUCH more comfortable. The only downside with the new Corbeau seats is I sit a little higher, but I'll happily accept that over discomfort. The Youtube video can be found here: https://www.youtube.com/watch?v=wPyttKPktXA
    • All 3 I guess. The car came with the JASI Aero 4 door Type R Full Kit unpainted so this was one thing at the top of my list to complete then I noticed there were body panels parts for this kit so i picked them up along with some black mesh to fill in the front bumper and front side air vents. car is at a paint and body shop atm completing this work. Next I will be addressing the internal bells and whistles, great summer project I can do with the kids.  full interior removal - ,boys car sound deadening - pads and spray ,boys stereo, sound, lighting - Big 3, GTT or bigger alternator ,kids head lining - dye black add star lighting mod ,daughter. That's it for the next 5-6 months. I have some motor maintenance  work i have to plan out. oil filter relocation, gaskets, mounts. beyond that, mind is starting to turn over if i can use a DET intake plenum, block off turbo ports & pipe in a air intake.      
    • roller coaster of a ride. Alarm system was removed & main harness was repaired where possible. still no fix just random successful starts. moved on to the replacing the ignition switch and relay. well all this troubleshooting & repair has been going on, the car is at a paint and body shop being pushed around. Ive been going down there on odd days after work to get it sorted.
