YeaJimi Posted September 10, 2008 Share Posted September 10, 2008 Hello, I've got a 1979 daily driver 280zx. Recently when I went to crank the engine over, as usual I did not hold it long enough and it did not start. So like normal I went to start it over again. This time as I cycled the key from Off -> Acc -> On, my voltage dropped (to roughly 3-4 volts) and lights dimmed. I ended up rotating the key all the way through the cycle and at the start position the situation remained the same. From what I can gather, I have a component that gets power from the IGN wire on my tumbler, and then is having a major voltage drop, sucking up all the power. Does this sound correct? I need to track this electrical problem down and if anyone has any ideas, please share them. Quote Link to comment Share on other sites More sharing options...
roger.svoboda Posted September 13, 2008 Share Posted September 13, 2008 Do you have a good battery (load tested) and battery cables with no corrosion. Start there. Basic stuff first. Quote Link to comment Share on other sites More sharing options...
91_4x4runner Posted September 13, 2008 Share Posted September 13, 2008 Verify that the cables are secured on the battery very well. Quote Link to comment Share on other sites More sharing options...
YeaJimi Posted September 14, 2008 Author Share Posted September 14, 2008 Update, Turns out my wideband O2 had a short and was sucking up all my voltage. Thanks for all the help guys. Quote Link to comment Share on other sites More sharing options...
