ls1king000 Posted November 14, 2009 Report Share Posted November 14, 2009 (edited) Today I took out my crappy cracked dash of my tahoe and replaced it with a newer 98 style. I disconnected the battery, unplugged all the harnesses (lights, switches, thermostat, etc) and removed the dash. The only thing I removed from the system was the iva-d901 and rux-c701 faces. Both "brains" sit under my drivers seat. Hooked everything back up.....NO illumination, NO screen display, NO power but, the screen opens and closes and beeps. I've already traced all wires to make sure they are not hung up or spliced by a sharp edge during dash installation. I rechecked all the ground wires from when I had to disconnect them to take the dash out. HELP, please! Edit: I checked the fuses, all were good. I disconnected the face and reattached it and now Illumination comes on for a second, then I here the relay for the capicator "click" and repeats every few seconds "on/off/on/off".

ls1king000 Posted November 16, 2009 Author Report Share Posted November 16, 2009 Dang it!!!! I replaced the battery yesterday (lazy sunday). Everything was working fine. Played a few tunes and drove around a bit last night. Then this morning, it was hard to start but, did. After it started, idle was rough. Then rougher, then it was dead. Now, I can get it started but once it's running the idle drops down and it dies. Alternator right? Well I took my 200amp load boss to have it tested and it turned out @ 195 amps so, it should be good. What the hell could be wrong with this thing? New battery, alternator is good.....what should I look for next? I'm lost. And confused.

ls1king000 Posted November 16, 2009 Author Report Share Posted November 16, 2009 OKay, I let the batt charge until 10.5v or more....starts....idles screams the rpm's.....drove it. As I drive it....slower and slower acceleration. Then back to 9.5V...and dies. Has to be the alternator, no!?!?! I'm no expert and really cannot afford a mechanic right now. I have lots of tools and I learn fast....anybody please help.

Beanz Posted November 16, 2009 Report Share Posted November 16, 2009 that does sound like your alt but if its seeing a load maybe you have a loose connection to your batteries.do you have anyother batteries besides the one in front? Quote That's why they don't deliver. Yer ass better go sit along the side of the road and wait. You can't expect them to travel up some dirt road in a hick / back woods town. Thats how horror movies start I explain things very simply and use analogies in terms of Pickles, and grape drink, pool noodles and jackhammers...if you can't put 2 and 2 together there man, There simply is not much more I can do.

Take your multimeter, with the engine running at idle, connect the negative lead to ground and your positive lead to the Alternators Positive output, what do you get? Then do the same measurement at about 2000 engine rpms. If you have low voltage at idle and normal charging voltage at 2000 rpms, your Alternator is not charging at idle or low rpms. Something to try.... Edited November 16, 2009 by bobonit Quote 97 Maxima SE Bunch of shit going in, check out the build Build Log Link to comment Share on other sites More sharing options...
ls1king000 Posted November 16, 2009 Author Report Share Posted November 16, 2009 I have a small second battery but, I disconnected it temporarily until this is figured out. One battery. My stereo is off, all accessories are off. Connections are good. I even replaced alt. to batt. terminals and wire because it was looking a little shady. I've heard some bad things about my alternator company (loadboss or alterstart) but, it has served me well pounding for 14 months.

ls1king000 Posted November 16, 2009 Author Report Share Posted November 16, 2009 I went to Advanced, Auto-zone and Dipatch.....passed all tests. So, again I put back the alt with batteries fully charged. It started with a slight hesitation but, did start. I run up front to get a reading on the battery, it already reads 10.5 then 10.2 then 9.8 then 9.5 and then it dies rather quickly. Much faster than yesterday. I can't even get a chance to rev 2000rpm before it dies.

maniac74 Posted November 17, 2009 Report Share Posted November 17, 2009 (edited) its possible your alt is ok but your battery killed a few cells which wont allow it to take a charge. did you try a different battery up front? sorry if i missed it. edit just read through that its a new battery, you sure you have all your alt wires hooked up?
