#36 of 111 Re: 1995 GMC Safari Radio Clock [hy4woj] by rabarrett Oct 25, 2007 (3:45 pm)
Replying to: hy4woj (Jan 20, 2007 1:17 pm) Normally, the clock should continue to run, but the display should go dark when the key is removed from the cylinder. 250 ma, or .25 amps is excessive, regardless of the vehicle in question. This can drain the battery, and can permanently damage the battery. Try disconnecting the fuses for the clock and the radio, and check for the drain again. It is possible that there is a connection problem on the radio, causing it to draw current with the key off. Ray

Replying to: grwilson224 (Dec 26, 2006 3:45 pm) GR,   Most of the time, the computer part number is on the computer itself. If you describe the issues you are experiencing, I can help you solve them. Ray

Replying to: squarepeg (Sep 26, 2006 11:43 am) These issues appear to be related to the BCM, or body control module. Your description of the issues experienced lead me to suggest checking all of the vehicle's grounds. Ray

Replying to: jcavaness (Feb 08, 2007 6:32 am) JC,   Normally, the fuse box is fed by what is described as a fusible link. This link appears as a large wire, red in color, and burns through in the event of a short. These links are typically connected to either the starter, or directly to the battery, and cab be checked by gently pulling on them. If the insulation stretches, the wire is burned, and it can be reconnected using a yellow butt connector. Do not bypass the link, as it is the circuit's only protection, and if bypassed, can lead to a nasty fire. Ray.

Replying to: albedo039 (May 14, 2007 3:43 am) It is likely that the bulbs are causing the circuit breaker in the switch to cycle, likely due to the draw of the bulbs. You may need to run the bulbs to a relay, using the switch to power the relays only. Ray

I went to start my van last night and didn't have any power to the headlights or ignition,everything else works fine I just lost all power to the headlights and ignition system.The van cranks just fine but isn't getting power to the ignition to fire it and I don't know what that has to do with the headlights.The book says there is a 40 amp battery fuse under the hood but I have never seen it that would explain the headlights and ignition but finding the fuse is the next problem.I just wondered if anyone out there has has the same problem and had to locate this fuse.Any help would be greatly appreciated.             dlm1 Replies to this message: v_chuck (Feb 19, 2009 4:51 pm) dlm1954 (Apr 15, 2009 1:19 pm)
