as the title states im having a problem after fitting a brand new bosch alternator to my r33 gtst to replace the existing factory alternator. I did not have any problems with the battery or charging prior to this. I have the battery factory located in the boot and noticed after driving today that it was extremly hot to touch and liquid had started seeping out from it even though its one of those maintenance free batteries. Just before taking it for a drive I started it up to make sure everything was good and let it sit for a few hours then went to touch the alternator and it was still really hot. like it was still charging the battery or something. when fitting it I disconnected the battery as per usual and followed all the instructions, tensioned the belt correctly etc. I noticed on the factory alternator it had 2 cables screwed to it. a bigger one which goes to the battery and another little cable which screws to the alternator housing for grounding or something. but on the instructions with fitting the new one it only had the one big cable and plug connected. I'm thinking there is either something internally wrong with the alternator or that little cable wasn't meant to be fixed to it. anyone had any experience with these bosch alternators or has a picture of there install? it would help me out immensely. Thanks

It's a bit hard to work out what you did, but if you connected an earth to the big lug that would be whats going on. Try and remove the small connection and see if it still charges.

I would say the battery is fubbarred already by what you described

      Good points thanks. Unfortunately I can't seem to rename this or delete the topic. Seems like I'll ask the moderators to change it or delete it.

      You might want to update the thread title.  V37 ≠ V36.  And it probably isn't a G37 unless it is 2012+ Ininiti or LHD.

      Just a basic run down of the relevant bolt-ons. All e85 First graph 406.9whp is HKS GT-RS, HPI manifold, 3" bell mouth dump / 3" straight through fake cat / 3" all the way to the rear and no resonators, nismo 740cc, walbro 460, oem RB26 itb's, power fc, eboost2, Greddy Spec M fmic, poncams, Turbosmart actuator, splitfires, ARD 150amp alternator. Blue line is same as above but Blitz Dual SBC (before i upgraded to eboost2) and 100cell "high flow" cat. Red line is after installing eboost2 and the fake 3" cat (it's just a 3" pipe with a cat shell welded onto it). Huge gains in response, as can be seen. Black dots are a mates sr20 with almost identical setup but uses a garrett 2871 instead oh HKS. Next grapghn 466.6whp is same as above, but HKS 2835 Pro S with the larger .87ar turbine housing, the special HKS Pro S dump pipe into a HPI split dual 2.5" front pipe and the rest stayed as is. Red line is after I welded the actuator brackets. (It was originally bolted together and was moving a couple millimetres under load). Green line is obviously before I welded the bracket, no other changes. 100whp gain at 3750rpm, massive gain for such a simple fix. Third graph is my current setup, huge changes. 469.7whp R31house twin scroll manifold, twin TiAl 38mm gates, Forced Performance (USA) HTA3076 with 1.01ar twin scroll rear housing, Link Fury+ and loom by 12volt, PRP trigger kit and r35 coil kit with r35 splitfire coils, HKS step 1 vct staggered cams, new oem lifters and performance springs, 49mm itb's w/port matched Nismo plenum, twin walbro 460 surge tank setup + 1650cc injectors, HKS Type R S13 600x300x103mm fmic, individual egt's, 4" turbo back with no resonators or cat and AES true straight through muffler + 4" butterfly off the dump pipe lower 90° bend. It's a preliminary tune with no boost control with using 20psi gate springs and 4" butterfly closed. Once body loom and PDM is compete, will go for 30psi tune.

      Power light apparently functions as a transmission error light, you can try the power sequence to read any codes from the transmission control unit.
