Hello, I am new to the site, and hope you guys can help me out with some electrical issues I have been having with my toyota tacoma.
I am not very good with electrical issues, so please bear with me.
I have a sputtering or surging at hot idle (and its driving me nuts!), mainly when my head lights are on. I checked my voltage from positive to ground at hot idle with the headlights off, and am showing 14v, but with the headlights off, it shows 13v.
Next, I pulled my neagtive terminal off of my battery, and measured resistance between positive and my block, and it was showing apporx. 22 kilo ohms of resistance. This shows that there is some, however small, current between the positive and negative wiring... Is this normal? Or should resistance always be infinite in a measurement like this?
Anyway, at this point I began pulling fuses, to see if I could find where the crossovers between positive and negative are. There were a few that seemed to be the biggest culprits, but the best I got to was about 120 kilo ohms with those fuses pulled (some fuses made zero change is resistance when pulled)...
Am I going in the right direction with the troubleshooting, or am I wasting time?
Any suggestions??
Thanks guys.
I'm assuming you meant with your headlights on your voltage drops to ~13V. I would start by having your battery load tested and having your alternator tested as well. Basically a charging system test. There are a myriad of electrical gremlins that can come from a bad battery or poorly charging alternator.
