Re: Headlight upgrade
The problems with dim headlamps:
1. External reg'd alts put out less voltage, especially with more electrical loads applpied.
You can check this voltage at the battery posts, or, at the headlamp socket.
2. Along with #1, the lamp power goes through the firewall twice, battery to h/lamp switch to dimmer sw to lamps. Dimmer switch might need replacing.
Measure voltage at the h/lamp socket and you might see 11+ volts.
A couple of fixes are install an internally reg'd alt and/or wire in a relay for each h/lamp using localized power, ie, pass side junction block for pass h/lamp, horn relay buss bar for drvr side h/lamp. And of course, ensuring a good ground is provided for all circuits to complete the circuit.
There are halogen lamps on the market as well as HID's, high intensity discharge lamps. There will require localized power due to the current drawn and h/lamp circuit becomes a control circuit instead of a function circuit.
Brain & I wrote at the same time. Yes, as Brian suggested, installing an electronic VR, Wells P/N VR715, does improve the performance of electrical system, plug & play.
