I just installed a brand new optima batt. in my 88' fj62. This trucks wiring harness is completely clean/unmolested in any way. A few days after install (first time driven with headlights needed), when the headlights are tuned on EVERYTHING else elec goes dead and the headlights are not on. When lights are tuned off, all elec. seems to work. The cruiser turns over very fast, the batt is not weak by any means and all the fuseable links at the batt are good. Another wierd thing, when the lights are tuned on, the turn signal indicaters and hi-beam indicator light up!? I know these cruisers are known for bad headlight harness's. I am checking the relay next, Any input would be greatly appriciated!
