  1. That is a bad break. I was hoping that you found the problem and it was something simple. Wondering out loud that they didn't put the wrong damper on the truck? I guess if that was the case it would have shown up immediately after. Do the mechanics not road test it after it's been through the shop?
  2. Well, it's been three weeks now. What'd they find?

    Ch 613 Won't Start With Key

    Mine doesn't have a battery disconnect on it. Anybody have the wiring diagram?
  4. My 1990 CH 613 sometimes will not start with the key. You can jump it across the starter and it'll start right up. I've noticed that sometimes when you turn the key to the on position, none of the gauges or buzzers come on either. I can hear a loud clicking every time I turn the key on. I assume that's the constant duty solenoid. Is there a relay after that solenoid that could be bad? I noticed that solenoid is awfully warm after a while with the key on. I've checked the battery cables and they're tight and I don't see any bad wires or connections. This is an intermittent problem that seems to be getting worse. Usually it'll start up in the morning with the key when everything's cool, but won't after that.
