Harrison M300 Issues? Not working.
Just picked up a 1978 era Harrison M300. I have not been able to get it going. Everything appears to be wired correctly for 230v 3 phase. Running a rotary phase converter.
My main question is there is a small FNM fuse block on the transformer. It currently has a 2.5 amp fuse in it which is what I want to replace. As I was going through the wiring diagram that was with this machine, I saw the fuse and it says "bussmann or equ. .... and 0 5 amp". Can't tell if it's 0.5 or 5 amp. It most likely is 0,5 amp. Assuming that's English for 0.5? It currently has a 2.5 amp fuse and was claimed to be running. The guy I bought it from didn't know left from right.... literally. He tried running it on single phase 220v with a 110-220v transformer. He gave up after he instantly blew the fuse in the purchased transformer.
The above fuse and the power light on the machine are the only two things that I can replace before replacing magnetic switches. Motor is wired correctly too.
