At first I thought my battery wasnt holding its charge. But with my new setup I found out with a multi meter that power is dropping as soon as the engine is off.
I did a parasitic drain test and discovered that by dis connecting my alternator, it stopped dropping!!! WTF???? Can somone pls explain as to how its possible my alternator is draining power when off? This post has been edited by yellowchinaman: May 22, 2014 - 12:07 PM |

QUOTE (Bitter @ May 22, 2014 - 1:14 PM)  How much is it pulling? About 0.1V every 20 seconds. Im watching it drop on the volt meter. Found this on youtube and its exactly the same http://m.youtube.com/watch?v=oHKUvB5oHIA This post has been edited by yellowchinaman: May 23, 2014 - 6:49 AM |
