Sun MDT distributor tester

I pulled the trigger and got one tonight. It spins when turned on but sounds like it needs bearings. The gauges are non working, He said when he turned it on the red lead was on the post and started smoking so now it has no power at that clamp. Hopefully one day I will find time to try and fix it.
