Can anyone tell me if this voltage regulator is original in my 3/72 240z? I bought a replacement at Napa thinking it might solve my bouncing tach problem, but it didn't. So i'm guessing this one still works fine. The replacement has the exact same housing and same style of plug. The one that was there to begin with also had an inline fuse on one of the wires. This Napa/Echlin replacement didn't. I replaced my 240z tach (which was shot anyway) with a 280z tach and I keep getting an erratic tach. It sits steady at idle, but if I really put my foot into the gas while driving, the tach will spike then slam back down to zero and start moving around erratically for a sec, th…

I read of people changing the alt. to another type. I once thought of doing that and learned these item I find of interest. The alt. as we know doesnt really produce at idle.The reason is the electric field it generates acts like a clutch on a go cart. The more RPM, the more the resistance. That said if you change the pulley and create resistance at lower rpm you can cause belt slippage, premature wear, power loss of the engine due to the increased resistance. Just installing anything on your car can cause more headaches than relief. Its a fine balance. Not to mention supplying 100amps to a alt wire that was only rated for 60 amps. Its just a battery charger. In most cas…

Hey guys. I just recently went to the radio that is shack, and bought a rocker switch for a fuel pump cutoff. The switch is rated at 30A, and 12v. Will this be good enough to handle the job? It has 3 "prongs" that you attach, or solder connectors to. They say Ground, Load, and Power. So if im right the ground goes to anywhere on the body, the positive goes to power, and the load goes to the positive on the pump? Thanks, as you can see im no expert

New car, stereo not installed. Everything works fine. Hey, I will plug the stereo back in! Plugged in: Stereo acts funky; Dome, fuel, and tach start to oscillate. All go out, including turn signals. I pull stereo, replace turn signal fuse with a 10 (wants a 20, I only had a ten), all systems back up. I take the stereo (and the car) to a decent audio shop and explain the situation. They bench test the stereo, say its bad (which I believe), so we put in a new deck. Couple miles down the road, all the same systems go down. I put in a 20A thinking that is the difference (I had a 10A) but it blows just the same. Obviously, stereo is interfering with the dash (afte…

I just put in a new / used fuse box from ebay wow what a diffrence everything is bright and works , only two things on the car that don't are the front passenger fender running light and the drivers rear back corner side running light . These are the side markers that are screwed in and have a lens and then a chrome piece and then the black rubber gromet. The ones that are not working on mine are very rusty and I was wondering how do the bulds come out? A twist type or a push in and twist or just a push in type < that sounded weird > . I have sprayed some cleaner on it to try and free up the bulb but still quite stuck and suggestions before I damage the marker?

I recently installed a zx dist. on my 72 240. I am using the gm modual method. My tach. now only goes up to 3000 rpm. I couldnt find anything related to this problem in the archives. Has this happend to anyone else? What may be causing this problem? Thanks, Dan BTW- some of you may remember me trying to figure out why my dual webbers kept fouling out plugs, it wasnt the carbs, it was the spark-thank god, plugs were getting expencive!-

I thought that I had seen a metal cover for the light but had never seen a rubber one. Does anyone know if this was standard equipment or an option. Thanks for the input.
