i got a new battery, H/O alternator, switched my big three, and bought a cap. what else can i do to prevent my headlights from dimming? any information would be greatly appreciated. thanks

As Richard Clark once suggested, if you want to stop your headlights from dimming, then put a 1F cap on your headlight power wire.....

 

would this also stop the dashboard from dimming?

you need a smaller pulley on your alternator. i'm assuming this dimming is when the engine is at idle at the stop sign etc. this will provide a faster turning alternator. say going from a 54mm to a 47mm like i did on my tbird it fixed the problem. HO alternators are great at cruising speed but do nothing at idle IMHO. you may need to purchase an externally adjustable voltage regulator. there is a company in las vegas that makes these but the name slips me mind at this point. good luck with this.

 

bigger alternator!
but
i like "As Richard Clark once suggested, if you want to stop your headlights from dimming, then put a 1F cap on your headlight power wire....."
and you can do the dash the same way

 

i just installed more batteries... (1 1000CCA Motomaster and 2 Yellowtops) have no dimming issues at all with about 2500RMS

 

what kind of voltage do you get with the car running?
how many watts are you pushing?

you should have very little dimming with the setup you show in the pictures

 

Look into a replacement or add on Kinetic PowerCells
