Post subject:  SlantSixDan Saves the day!

So the car has been running great and it's getting a lot of use. Still haven't got around to doing the HEI conversion but I did do the heavy gauge dual 50amp fuse ammeter bypass and let me tell you it saved the day! Dan I can't thank you enough for suggesting this while doing my alternator swap.

As far as I can tell the VR128 went tits up while driving around with the heat blasting and the lights on and with no ammeter I had no clue. Got home and when I went to put the car in the garage I had a dead battery. To late to investigate so I left it for the morning. This morning I threw the battery on the charger and found that the fuse at the alternator side had blown, saving me from having to rewire my car or worse.....

I put in a new fuse, stuck my meter on the battery and fired it up. 18+ volts at the battery! I had the VR101 on the shelf so I stuck that in there, fired it up and "viola!" 14.2ish. Reading at the alternator output I'm getting 15. Sound about right?

Thanks again Dan. So on my list now is a voltage gauge along with the HEI and that should be it for electrical.

Glad to have helped (yes, this is why we put fuses at both ends!). Interesting about the dead VR-128; what brand is it, d'you know?
