Restoration of a M38A1-CDN3 106mm recoilless rifle Jeep

Any issues with a short in the signals usually leads to a failure of the flasher. They eventually put an inline fuse into the system, and in Martin's case, it can be seen in the photo of the engine compartment just near to the flasher. While the entire light system is protected by the 20 amp (if I recall correctly) breaker built into the switch, this was obviously too high for the flasher to handle.

The indication that you have a short is that the indicator light on the signal switch will stay on. But that is also an indication of a overheated or failing flasher.
