I have a 84 c30 with a 6.2l the glow plugs wont work on their own I bypassed the thermo switch on the passenger side every thing else is new relay, controller ,glow plugs. If I ground the relay they work great I think I must have a ground problem any idea where I would find any and all grounds I'm out of ideas any help would be appreciated
