I'm in the process of putting my '89 K5 back together and was putting the doors in. I dont have the battery so I hooked the charger up to the battery cables. Everything was working fine enough and now all the sudden I'm getting nothing. The charger is going right into short mode. I think I may have turned the ignition and kicked the starter for a 1/4 second and that may be when I lost everything. I had lights, blowers, door locks, etc. in working condition. All fuses look good in the dash. Anyone have any clue as to what I can be missing or if the starter may have screwed something. Thanks.
