Carpenter Mark

I was working on my other vehicle with the Jeep (2001 GC, 4.0L, 208K) radio on ACC to listen to.. After about an hour the radio went off and the battery in the Jeep was too weak to turn over the engine.Surprised me, I didn't think the battery was that old. I then jumped it with my truck and it didn't want to keep running. Got it running after 1/2 doz tries, took off the cables, let it idle for 10 mins and took it for a spin down the street. Temp, oil press, alternator gauges normal but no tach or speedometer. It's dark now (no garage) so I can't see to work. Could I have blown fuses?
This sucks- got a Bronco plow truck I have to put a PS pump in, then exhaust, my truck alternator is on the way out and it needs a muffler. I've been counting on my Jeep......
