I found the passenger side horn (high tone) wasn’t working. Hooked up a test light and the wiring was good. Unbolted the horn and tested it anyway. Um, it worked. Put it back, and it works now. Huh, whatever works I guess. Was just about to order a hi tone and add a cheap air horn, but hopefully this just works now for a while. The connector wasn’t corroded at all either. Who knows

Came home tonight after being out of town for 5 days. Yukon sat at home while I was gone. Battery completely dead.:banghead: I’ll get the charger out in the morning I guess.
Put the charger on it yesterday and initial 20 min. drive everything was good. Went out yesterday evening and on way home volt gauge started moving around and a few minutes later dropped and got service charging system and battery light. This morning started it and alternator was putting out 14.2 v while idling for about 10 min. then dropped and battery light came back on. Battery test was doing weird stuff with my neighbors tester, so got a new alternator & battery and installed today. So far so good.

The ole girl had her 300,000 birthday a couple weeks ago! Been giving her some love for the big occasion. New ball joints in the front, rear end to replace the one that's been making noise for 20k miles (now with G80!), Rustoleum'd the frame, and more to come.

Here's to another 300k.

We just got a 2 post lift at work, and let me tell you that's been a game changer. I pulled my parts suburban in, pulled the rear end, pulled it back out, pulled my Tahoe in, had the old rear end dropped, and had the new rear end installed all in about 4 hours after work.

Next week we'll be doing taller lift blocks in the rear to make up for the sagged out springs and regular cargo load in the back. Front end alignment after that, and fixing the AC.

Hopefully in the coming months we'll get into some rust repair, rock sliders, maybe even replace the carpet and some upholstery repair on the front seats.

How many amps is the new alternator? I upgraded to the 160 amp a few years ago.

160. That was only option for mine. Not sure if they made all 05 use 160 or not. Or maybe all XL or Suburbans got 160. I thought my choices were 105 or 145 in my old 03 Tahoe.

Might be an intermittent bad ground on that circuit. See where the horn ties in to ground and check to make sure it is clean and tight.
