Re: 12v amps gauge

Facing front of ammeter, stock battery wire (yellow) goes to right side, generator wire (yellow-black) to left. Reverse those for negative ground.

Forget a shunt. Just makes normal battery...

Re: Fuel Bowl Question

Flare fittings seal between the mating flare joints. No sealant should be required, as Jim says. As long as the threads are good and surfaces smooth you should be able to pull in a good seal.

Re: alternator

The 6 volt pos or neg ground alternator is a conversion of the original Delco 10Si 12V negative ground, which are common as nails these days and can be had pretty cheap. Even the Asian knockoffs...

Re: Fun project voltage regulator

Snyder's sells a "Genuine Nu-Rex" regulator which may or may not be the FP with different branding. I would hope it's a different design internally though.

Re: using a 12 volt system with the 6 volt horn

If it has bullet connectors they can be hard to get to make contact when they're new, even if they look secure. Be sure they're mated all the way. Snyder's graciously sent me another horn relay...

Like I say, lots of fans. But technically it could have been done much better.

Re: Horn Wiring

The horns of the time were probably all series wound as Tom W says above, and polarity shouldn't matter. Your converter should be capable of at least 6 amps output, but a smaller one would probably...

Re: Fun project voltage regulator

FunProjects site has been out of stock for almost a year. The controller IC they use has been discontinued. I don't recommend buying it even if you can find one, although most owners seem pleased...

Re: Coupe back roll up window

Mother-in-law window. Roll down for conversations with rumble seat passengers. Roll up when you're tired of her yak.

Re: Coupe back roll up window

The PO put one in my 30 coupe. Said it wasn't easy. Probably why yours hasn't been installed.

Re: wiring harness

No lights or horn means the two yellow wires are open at the cutout terminal (running). If not running, could be open at the firewall or ammeter (or fuse).

Re: Any electronic experts out there

Aw, PalAl, never say die.

Could be the "backflash" from the ignition coil is killing the power to the control module. If so, a 5A diode between the coil and flasher/switch/acc/control supply would...

Re: 1931 Generator needs rebuilt ?

Before rebuilding you should clean between the commutator contacts and replace the brushes if worn down. Easy job.

Re: Which headlight wire for high/low beam

Re: Which headlight wire for high/low beam

32/32 should have identical filaments. You can flip it over if one filament burns out. Longer filament length = higher resistance, lower CP. Does it have a number on it?

Also be sure the wiring...

Re: Any electronic experts out there

Yet another option - run ground return wires in parallel with each signal wire. Do not connect LED end to chassis. RFI in both wires should cancel each other.

Re: Any electronic experts out there

So RFI appears to be the problem. Best to attack the cause with resistor wires/ferrite beads if possible, otherwise replace the signal wires with shielded wire. Ground all the shields at one end ...

Re: Checking 6 volt neg ground output with multi meter

7.1 is a tad low - 7.2-7.9 is min-max for good charging. Should charge the battery ok, but more slowly. Maybe much more.

Re: Electrical Question ???

Turn signal switch may have a pinched wire inside. The many wires are packed pretty tight.
