Re: Dim signal and brake lights
You might try setting your idle speed up a bit. The 6 volt generators show negative charge at idle with lights on. Experiment a bit. I am sure there will be other comments but this has worked for me. Might try this first.

Re: Dim signal and brake lights
Going to have to get the generator output up a little. Do you have really good connections and grounds? That will help, but will not make up for low generator output. Have you measured the output at idle and at say 1500 RPM?

Re: Dim signal and brake lights
JOE thanks but if I set idle up any more it would be to fast, J SEERY I have checked the voltage with a meter while increasing RPM. , what should the voltage at 1500 RPMS.be THANK YOU Sunshine

I had the same problem and I put an alternator on it and that solved the problem. I am not fully stock, so I'm not concerned about authenticity on that item.

Re: Dim signal and brake lights
J SEERY I DO HAVE CLOSE ED UPTO 7V. WHEN ENGINE IS REVVED UP . I am using 6v. cables, I checked my grounds. This truck has a home made harness there in may be the problem . I believe the alternator may be my best fix since this is just a driver.THANK YOU AGAIN FOR YOUR HELP SUNSHINE

Re: Dim signal and brake lights
Another option would be to change the pulley size on the generator so it turns over a little faster at lower speeds.

Re: Dim signal and brake lights
J SEERY YES IT DOES HAVE A VOLTAGE REGULATOR . OLD HENRY I GUESS I WILL INSTALL A THROTTLE CABLE WHICH I DONT HAVE NOW. thank you I AM NOT CONCERNED ABOUT MY HEADLIGHTS BECAUSE I SELDOM DRIVE AT NIGHT . IT IS THE SIGNAL AND BRAKE LIGHTS DIMNESS IN THE DAYLIGHT WHICH I AM CONCERN. thank you. SUNSHINE

Re: Dim signal and brake lights
The voltage regulator can be adjusted to increase the voltage output, but the idle output has to be balanced with the higher RPM output.

Re: Dim signal and brake lights
Are there smaller pulleys available for generators?

Re: Dim signal and brake lights
I don't always use the throttle cable to get the generator charging. Sometimes it's just a little pressure on the gas pedal that gets it going and keeps it going while I'm sitting at a light.

Re: Dim signal and brake lights
My three cents having raised in the 6vt days , something is defiantly wrong.
I'm positive you have leaks and or ground problems. Corroded bullet connectors wrong gauge wires wimpy batt. the battery is a voltage regulator too. My 23 Ford lights are bright as the sun whether running or not. And these only put out 10 amps if lucky and I have no brightening or dimming with rpms. Case #2 46 V8 bright as the sun no brightening or dimming with rpms. I would check voltage at the rear lights engine off then engine on. I bet that will be surprising. Next common thing we see now is junk batterys. Went through that yesterday with a fairly new 6vt commercial. They tend to get a surface charge which tells the regulator that its charged when its not. A good healthy battery will provide bright lights with engine off for quiet a long time. With that said you should not have lights going to dim for a few minutes at a stop sign, meaning you are using quarter of the battery, thats where that surface charge or false charge comes in. Oh it may start fine but way down there in the battery its doing nothing thats a classic case of getting brighter with rpms that means the generator is rapidly replacing used up volts sitting at a stop sign few minutes so of course lights will brighten. Hope I wrote this right. |
