Truth of the matter is, I installed an internally regulated alternator off of an 83' l28et onto my 75'280 with no idea I now had two voltage regulators in the system...until, I fired up the car and the amp meter went haywire. This led me to research the following links: http://www.zcarcreations.com/howto/voltreg.htm I matched the yellow and white/blue stripe as instructed as the voltage regulator harness matched the info provided, but after realizing the system wasn't charging, I searched further: http://forums.hybridz.org/topic/108455-75-280z-alternator-upgrade-to-zx/ http://atlanticz.ca/zclub/techtips/alternatorswap/index.html All three agree that the white/red and the white/black are joined. Two out of three state the yellow and white wire should in fact be joined. So I did. Still not producing 14.4 volts. To make matters worse, my digital meter was lying to me saying it was overcharging, until the battery died minutes later. After installing a new 9 volt, it actually showed 10.5v proving it wasn't charging at all. Even after giving some rpm still no change. Neither combination seem to yeild a positive result which leads me to believe that either I've damaged the internal regulator or it didn't work to begin with...I'm leaning towards the latter. Times are tough in Alberta right now, blew my budget on a pallnet fuel rail and arp head studs for the l28et. I'd like to use this alternator for the time being until i can afford a larger amp version. Can I solder the original voltage regulator back in the system, or any other low budget option would be greatly appreciated. Thanks in advance, Jason
Car is no longer charging. Can anyone tell me what the role of the Black/Yellow wire is, going to the voltage regulator on a 260z? According to the factory wiring diagram it goes straight to the interlock relay. Is it supplying voltage TO the relay or is it receiving voltage FROM it? For context, here's the issue I'm having: I get 0v at the WB and Y connectors (these run to the F and N terminals on the alternator) There is 12v on the W wire at the regulator. The B wire is showing a strong ground. The BW wire runs inside the passenger compartment and becomes the green wires on the Tach, Amp/Fuel, and Temp/Oil gauges The BY wire connects to the interlock relay. Still trying to wrap my head around those last 2 bullet points. I have to admit, i don't understand why those any gauge besides the ammeter needs to be connected to the voltage regulator. Not sure if this is significant or not, but the BY wire reads .059 volts when the ignition switch is on. I am tempted to jump 12v to this wire, to see what happens, but i'm afraid of hurting the regulator, if it is isn't defective. Any advice is greatly appreciated!
