I'm in the process of making wire harness changes that include upgrades and additions that will increase the total current requirement from the alternator/battery. Ultimately, besides wire gauge changes, the alternator will need to be upgraded. For this calculation, I started with the belief that winter and summer might be very different. Turns out, maybe not so much. Loads are computed at minimum charging voltage: 13.5 (arguably). Lighting current is based on using incandescent bulbs which also will see "persistent" and "transient" use. The persistent load comes out to about 17A, while transients total around 16A. I took a WAG and chose 25A for both. Some other transient loads, such as power windows, are not included. Audio equipment is not included. The highest load case in this example is 134A. If you believe in safety factor, and I most certainly do, it looks like I'll need at least a 150A alternator. Has anyone successfully used an alternator rated in the 150 - 200A range?

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

I'm looking for an ECU and paired harness for an '83 L28et, it is my understanding that any of the years are compatible as long as they have the harness from that year as well. I have the 5spd but I believe the auto ecm works as well. Any advice on where to find one for relatively cheap would be welcome as well. thx!

I'm in need of an ecu wiring harness from a 1983 280zx turbo in good condition. Thanks.
