Carl, Remove both fuses, thoroughly clean the contact surfaces on both fuse ends, and the fuse holder contacts with an abrasive cloth then reassemble.? It is very common for in-line fuses to develop a bit of corrosion at the contact ends.? Also, not a bad idea to replace the fuses as internal resistance may also be involved.? Fuses are to protect the wire, they do nothing for the radio other than preventing wire overheat or fire.? ?I remove those fuses entirely for base station applications, and for mobile connect the positive to a vehicle fused battery circuit if possible and negative through a blade type fuse at the ground contact end.? Those fuse holders are available at most auto parts shops.? Fuse holders should be as close to the power source as possible.? you have found you're easy to fix problem.? Good news is the radio hasn't decided to do a low voltage shutdown thus far.? Regards, Phil / K4PO
