Dunno if anyone has followed my horrors of alternator and belt squealing. Anyways, I put in new alternator with new pulley and new belt, along with new water pump. No more squealing and its charging 14.3-14.5. Even my dual batt setup is charging fine. Now, ive got 2 55watt driving lights and 2 135watt KC 8" lights. They are wired together to one switch. I believe they each have their own relay, but not 100%. When I put on off road lights weather headlights are on or not, the volts drop and the alt. kicks in tryin to keep up. Could jus a pair of off road lights cause this much draw? Also what about splices and wiring. I use crimp connectors and my wiring is clean and well routed, but I do have a few splices in it. Can this cause power draw above and beyond the lights themselves? Im jus tryin to sort this out so I dont have more drama. Thanks.
