I did a voltmeter check tonight when everything was just barely warming up, while running. From a long pigtail attached at the VR IGN, I measured 13.99V to 14.00V when grounding at the battery. Between VR IGN and the VR case was exactly the same at 13.99V to 14.00V. All this while the battery...

An answer has been found.......or at least a solution possibly. I'm going to say cautiously that both cheap voltage regulators were(are) junk. Some day I'll try them out in my '75 D300 dump truck to see what happens. I had run it the other day when the temp was back down to 9 degrees F. With a...

Now it's back down in the 30's temperature-wise and I'm seeing high 14's but not 15V at cold startup. Once it warms up it settles down to no more than 14.62V. This all seems really good but I'm not sure what I did to "fix" it......The only thing that I did was to clean the cables and terminals...

OK, so I'll try to do the voltage drop test tonight, but here's some new info. This past weekend when it was 60 degrees compared to "normal" 20 degrees for Dec/Jan in Vermont, I re-installed my almost new battery and fired it up. 14.7 V stone cold......not so scary. At high idle it started to...

Last night I tried a battery from car that hasn't been used much recently......measured at 12.4 V. Starting up it read between 14.7 and 14.9 right off, but by the time the choke opened up, there it was jumping up over 15 V again. I just bought a new multi-meter and I have an adjustable VR on...

With a just-charged battery at 13.1, I measured 13.0 at my ignition circuit connector and got 12.8 at the blue field wire connector.......this with engine off but ignition on, grounding off battery or my 10 ga ground stud.

So, I added a 10ga ground wire from alt case to VR to battery to no avail buts it's still a good addition to a rusty old truck....still getting 15.1-15.4V at battery posts with and without loads. I can get a V reading off the splice of my new positive VR (blue wire) connector......is that a good...

I have not had time to get back out with the volt meter, but I have several things to try, thanks to all. I'll get some photos and show where I get what in a couple of days.

Thanks to all, this gives me a few things to test. I've had my share of Mopar truck amp meter meltdowns. Being a pretty whipped northeast vehicle, the harness became unworkable so I've been plowing for the last two years, running off a relay switched marine fuse box that I run only start...

So, I have checked in now and again for Mopar tips, and the crew here has been extremely helpful over the years, even though I no longer have my '69 273 Dart. I'm currently running a '72 Dodge W200 (318/727) plow truck and having overcharging issues. I have a new parts-house rebuilt...

OK, so I've been doing great with a bone stock '73 318 electronic distributor wired to a GM HEI module on a heat sink using the correct coil for such an arrangement. Accidentally left ignition "on" for several days and now she's quit sparkin' altogether. For 10 points….what did I fry? Got two...

Thanks, that's what I thought. I had the 83 manifolds surface ground and will assemble with 360 gaskets against the 318 heads. I will then have my pipe bender guy build me a stainless 2 1/2" dual system with either an X pipe or H pipe, the idea being to build a good exhaust system once for a...

A small apology for a non-A body Mopar small block exhaust question. So, I'm wanting to put 83 truck ex manifolds (from 4bbl 318 w/air injection big port heads) on my 72 truck 318 with stock heads. The air ports shouldn't matter and I'll get to use bigger down pipes. Then if I go with a 360...

This morning I took apart the firewall connector that includes the biggest red wire right off the starter relay (the one with a fusible link) and voila! Once I cleaned both sides of the firewall connector with electrical parts cleaner and a wire brush and pushed it all back together everything...

I no longer own an A-body (had a '69 273 Dart) but now run a '72 W200 plow truck with 318 and 727. Everything is basically un-molested original Mopar except for a homemade HEI conversion (many thanks to this forum). After experiencing occasional complete blackouts of the wiring harness, I now...
