Correct, they usually just short out and send AC volts everywhere.The benefit of rectifiers is that they never break...
There are good wet cell (add distilled water as needed) batteries available for $69 and up...3 years is the avg. life span of a good battery; why spend the extra money? Each season check each cell w/a 5 ball glass tube battery charge tester when the charger says it is fully charged. With 4-5 balls floating in each cell the battery is still good enough. If you find one cell w/darkened acid containing cell fragments, get a new battery because it is going to crap out soon.A new battery each year cost 100$. I like to replace them every year or so.
Excellent choice...it is isolated from the perils of the OB charging system and won't discharge the battery due to low current consumption.I will hook my fish finder to my other battery if I have to.
No, just the opposite...the fuse protects the boat wiring and battery from an internal short or increased current draw from the fish finder. Since FFs are solid state, integrated circuits they are quite reliable.My fish finder does have a fuse though. won't it blow before i ruin the fishfinder?

This is all great information. I just rec'd a price for a new voltage regulator which is on back order. 193.00 plus tax. With no guarantee it will last. A new battery each year cost 100$. I like to replace them every year or so. I just want to go fishing without that stupid alarm going off. I will hook my fish finder to my other battery if I have to.

Make sure you apply the heat sink dielectric grease to the base/back of the regulator when you install it. If the seller did not include a small foil pack of it w/the regulator you can buy it at any electronic store.I just rec'd a price for a new voltage regulator which is on back order. 193.00 plus tax.
agree guyjg....the rectifiers used on these rectifier only systems run so hot when everything is running normal that they use the motor block for a heat sink.....we not talking cape canaveral quality here on these rectifiers......i am outa here on this discussion...enjoyed and always learn something.....
