Since I've installed my UD pulley, I've had a problem with voltage spiking at idle. (especially with stereo or KCs on)

I upgraded to a 145 amp alternator, and already have a redtop optima. I'm going to upgrade the wiring tomorrow, and was wondering the best way to do it.

Should I run a new cable from alternator straight to the battery (I would use the unused top post on the optima) or to the red-plastic covered auxiliary post?

Are there any other cables I should upgrade? (ground, other power wires)


pics would be helpful of setups...THANKS!
