When you say "deleted" did you provide an alternative fuse/ breaker? VERY dangerous. Those old girls are not well protected in the fist place, and removing the fuse link adds a LOT of room for a Great Big Failure

So you bypass that and now none of the ammeter wire is protected, nor the bulkhead connector, not the ammeter, nor the wire going back out to the alternator. The headlight circuit has a breaker in the switch, but the wire from the switch to the splice and back out to the battery is not protected. The wiring to AND FROM the ignition switch is not protected, nor the main feed to the fuse panel "hot" buss.
