2000 S-10 Blazer. I have had a battery drain problem for a long while. I put a battery shut-off switch on the ground post. which saves the battery.
now a new problem. the Blazer just dies. all the lights on the dash comes on, the radio clock goes back to 1:00, which means [I think] a major disconnect. it will start right up, but the radio, being off, makes noise [remember in the old days when the AM radio had spark plug wire noise and sounded like an audio tach!] ya it's like that.
when I got home, radio noise still happening, I pulled the radio fuse, which stopped the noise, but all the dash gauges quit working [so I cant do that].
I have cleaned the battery terminals, and the cable to engine ground. today [after it warms up]I am going to ck. the + cable at the starter.
is there a ground wire under the dash? if so where? is it possible to find the hot wire to the radio [not much room under the dash to see anything]
I cant drive this anymore as it is unreliable.
any thought will be appreciated.
thanks Rod in AZ

Be sure to check the grounds on the back of the heads....often overlooked.

I had previously put a battery disconnect on the battery. I checked it yesterday. the knob tightens the two parts together. as it was, there was a high point, which was all that was making contact. a far amount of arcing on that. so a bit of file work and I added a brass washer to make better contact. havent tried it yet. maybe Tuesday.
will post an update after that.

There's a short somewhere. Problem is finding it. Wiggle the harness. Especially around the passenger side head. I've seen a few harnesses rubbing against the head or brackets.

so I filed the contact point on the disconnect and added a new brass flat washer. I have driven it 130+ miles now, and it runs fine. so the problem was lack of good ground side contact. I will just have to live with the battery drain. I was told that the stepper motors, somewhere, are the problem. the money to fix it are just not worth it.
more new car cheap junk.

Told by who? Start pulling fuses one at a time to isolate which circuit is the problem, and start from there.

I had previously pulled all fuses. the problem lies with the radio. when that fuse is pulled the dash gauges go dead. that wont work. some day when it is warm, I am going to try to find the power wire to the radio and disconnect it. the radio, when OFF, makes a noise like an audio tachometer. I am going to bet the wire cannot be found, as there is no room under the dash.
I am going to try the shop that sells high dollar radio/speaker installs. maybe they will know.

Pull the radio. Unplug it. Leave it unplugged and drive it. With adapters, you can replace the radio. I installed Pioneer stereos in both my Jimmy's. Even installed XM radio on the '95.
