Hi, i here have a Raymond r40tt and Came into the shop beacuse a no power condition, i found that the line filter fuse keeps blowing with no apparent reason, i have checked everything and found no signs of shorts no wires burnt or chaffing so, i'm getting frustrated, Also a resistance in the Main board is getting really hot is the one ontop of the conector that comes from the encoder, i heard something about the voltage being low and causing that fuse to blow, i don't know how to configure the low voltage cut off, any help would be appriciated
