Ammeter doesn't show discharge with lights on
The ammeter on my 30 RHD Phaeton doesn't show discharge when I turn on the lights whether the car is running or not. It show charge of about 10-12 amps a road speed. There is only one wire,yellow/black, hooked to the cutout. The cutout is a rectangular box,about 1"x2"x1".
Something must be incorrectly wired ( I didn't do it!) Help! |

Re: Ammeter doesn't show discharge with lights on
There should be three wires at the cutout. One going to the junction box(which I
think you have), one to the horn and one to the light switch. Bob |

A quick search here should provide a wiring diagram.

Re: Ammeter doesn't show discharge with lights on
It sounds like someone may have connect the lights to the starter switch instead of the cutout.
At the starter switch the ammeter would be bypassed. |

I don't think he is saying Tom's answer is wrong but the way the car is
wired is wrong. Bob |

Re: Ammeter doesn't show discharge with lights on
Down in the DEEP DARK woods, people did a lot of "off the wall" things, to get BRIGHTER LIGHTS!---Heavier wire, shorter wiring, headlight relays, etc.
MANY folks would NOT EVEN travel at NIGHT! It was common, to have a car that didn't even have working LIGHTS! MANY didn't have the skills to repair them, or MONEY to pay someone to fix them. Chief once traded a light repairing job, for a 1/2 grown HOG! I tole you I wuz OLD. Bill W.

after about 2000 every car already used a relay in the fusepannel under the hood and very little gain is noticed.

Re: Ammeter doesn't show discharge with lights on
By the way, you should cut back the output from your generator unless you drive lots of short trips with your lights on, even then it might be a bit high.

Re: Ammeter doesn't show discharge with lights on
Depending on what they cobbled up, probably some DID & some DID NOT. Most "probably" didn't care, as long as it started every morning. My first Model A didn't even have a needle on the AMMETER, when I first got it! Found one from an OLD tractor
