When I fire up my machine, it only runs for a short time when I pull the trigger. By short, I mean about one second or less. I've checked all the connections, and wiggled the blue wires that go from the gun to the circuit board. I took the gun apart, looking for melted contacts, etc., but nothing. After a while, it will come on and work.
I need to take it to the shop and have it fixed. But I'm wondering if there's anything that I may be missing that's obvious or a simple fix.
