Miguels Posted January 2, 2012 Report Share Posted January 2, 2012 hi guys, i just installed my HO alternator and noticed that my dash lights are dim and when i accelerate they go bright. also i am checking my voltage and its sitting at 14.5 and it jumps up to 16 volts for a quick second then goes back to 14.5. i also changed my wires to 1/0 gauge but went straight to the battery and not the distribution block you guys think that could be the problem? fyi the stock alternator never did that so im guessing i might even have belt slip because the pulley is much smaller than the stock one and has very little contact area Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...

Miguels Posted January 2, 2012 Author Report Share Posted January 2, 2012 its a 1998 ford expedition and the alt is a 300a and does 240a at idle so it should have the power to not have any lights dim, my dash is dim without anything being on just the lights Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
