Recently upgraded my radio box (see what have you done lately) and cannot figure out what happened. Images show before and after change, problems are now have dim spreader lights fore and aft, dim helm light. Radio seems to work fine, with the exception that when I key the mic it goes to the local noaa weather station. There is no voltage drop seen on the meter when keying the mic or turning on the spreaders or helm light. Previously all were wired via the Blue Seas fuse panel. The conversion to breakers and switches is the major mod. All pos and neg daisy chain wires in new panel are 10 ga. Wires from load side of circuit breaker to switch and from switch to load are at least 14 ga if not more. The supply pos and neg wires are the same wires which powered the Blue Sea panel. All connectors and wire have been examined and seem fine multiple times. Voltage on meter shows 12.8 to 13 when on house battery, no engines running, and again no drops when powering up things, but things are dim. All other dc systems are working fine, helm panel, nav devices, etc... My thoughts are that my original pos supply was marginal and removing the Blue sea and adding switch panel increased resistance causing the problem. This supply wire originates from a pos buss under the helm on the starboard side. I believe the neg wire originates from a buss near the same pos buss.
thoughts would be appreciated.
