I bought my '73 GMC without ever trying to start it. It was parked and trying to start it was not going to do me any favors. I knew it was going to be a project. I had it towed to a storage facility. I checked to see if the onan was going to work and it was. I did the fuel system from back to front. Time for the 455 to be checked out. I pulled the fuel pump and figured out that I need to change the timing chain and gears. I changed the oil and filter. Put oil in all eight cylinders. Using a breaker bar rotated it to #1 TDC. Pulled the dizzy and pressurized the oil system. Time for a compression check. Put a battery in then put the key in the key slot and the buzzer came on. Turned the key and it didn't feel right and nothing happened. When I let go it didn't spring back like I am used to. I tried it a couple of times and it just did not seem right and nothing -- I mean nothing from the starter. I tried it with jumpers and got the same. I checked the voltage at the primary wires at the starter and it was only 6 volts. I pulled the starter and it did nothing on the bench. So I pulled the alternator and took both the alternator and starter to my rebuilder. My question is are the ignition switches common to replace and if that is necessary are there other issues I should check as I am going through this. I just want to cover the stuff that will give me problems later on while I am into the middle of this.

TIA
