i just bought a used 1995 FJV-20 milling machine and i got everything running just the cooling is giving me trouble. It will not send the command to the cooling contecter Coil to turn on the pump. If i press the contecter the pump turns on but in the programs it gives me a alarm and if i try and turn it on manual it sents nothing to engage the contecter and to turn on the pump

Any ideas
