Alright, so you guys really got me thinking... Eagle, you suggested to advance the spark until my engine starts to ping, then back off a little. Starts to ping? I’ve never heard my engine do that when advancing the timing, and I always drive at full spark advance because it feels way...

This is a very helpful slide deck, thanks for sharing it! I learned a lot from this.

So, I did a few test drives today with different GAV settings, and it turns out I still get about 10 mpg even with the GAV at 1/4 turn and all the way closed. I know the GAV is doing something, as it instantly affects the engine power when I change it, but I’m confused as to why closing it all...

Hey all, thanks a lot for the suggestions. I have checked the speedometer (and odometer) against a GPS, and it’s pretty much spot-on. I also just checked my spark plugs, and there is some black sticky-ish residue around the edges — photos attached. Does this indicate too rich a fuel mixture, or...

Hi all! I have a 1928 Tudor, and I get 10mpg. From reading other posts and articles around the internet, I’m getting the impression that this isn’t completely out of the range of what I should be expecting after 93 years, but still seems definitely on the lower end — I see some people are saying...

Re: Keeps blowing fuses — alternator problem? Sorry for the long delay on this. A combination of major shipping delays and extended power/internet outages in my area set me back a month in fixing this problem! Anyway, I ended up replacing the whole alternator, and that solved the problem -- no...

Re: Keeps blowing fuses — alternator problem? Great suggestions from everyone. I’ll check for shorts in the places several have suggested, although if there is an intermittent short it may be difficult to detect under static conditions when I’m not driving. Other updates: I had the battery...

Re: Keeps blowing fuses — alternator problem? So I cleaned both my battery posts and the battery ground cable, sanded the part of the frame where the ground cable attaches to expose the bare metal under the paint, and ran a #12 wire directly from the alternator housing to the battery ground...

Re: Keeps blowing fuses — alternator problem? Ah okay, I understand now. So I see why that would prevent the alternator from blowing the fuse... would that also mean the ammeter would only show power being drawn from the battery, and not power going to the battery, since the alt would be...

Re: Keeps blowing fuses — alternator problem? Thanks so much for all the responses! I will try what Tom Endy suggested (wire the alternator housing directly to the battery ground, and clean the battery ground cable and terminals) and will report back with results. In the meantime, I also tested...

Keeps blowing fuses — alternator problem? My Model A is running a 12V system, with a 60A alternator using the one-wire setup. I recently replaced the coil, and added a ballast resistor. The next time I drove, the car ran fine, but when I hit about 50mph, the headlights blew out and a few miles...
