Lowrance HDS 12 Gen 3 Fuse Size - 06/05/16 05:04 PM
What size fuse is supposed to be used for the head unit on a HDS 12 Gen 3? I have searched the installation manual and did not see a size mentioned other than the network unit which called for a 3 amp. A 5 amp fuse was included with the unit I purchased but do not see anywhere in the manual to use that size. My unit all of a sudden has started pulling more than 3 amps but was working fine until yesterday and started blowing the 3 amp fuse.
