To the contrary my dear Watson, you see I foresaw the dilemma in my strategy and added a separate fused circuit that is also the same circuit as the radio memory....if those kill my battery I have serious issues.

Suprkoop,

Just to be safe I would take a VOM, put it in Ohms setting, and then (with the battery cables not connected of course) measure the resistance across the pos to negative cables. Make sure there is no low ohm measurement that would indicate a short prior to
hooking the battery back up. If there is a short, then you can trace it down by pulling fuses, etc. to see where the issue is. Might save you some trouble...

Sorry, Not a fan.

Sure it may be good for the catastrophic accident with a short, but I have had smoking wires from several cars over the years and it is always a small wire pulling too much current. A 16 gauge wire will burn way before the 150 amp fuse blows.

thanks, for all the good info, however I have broken down and used my essential worker bonus to purchase a new wiring harness, something I should have done a year or so ago before the body went back on and everything was out and exposed.

. So with that being said, and with the issues you historically have with wiring , you will be running BOTH! ,, and circuit breakers too,,
I must be doing something right,, electrical gremlins have stayed away from me ,,, I've burnt down cars for other reasons, but not wireing,,,

Yea, the double method is the safest, but I just use the green twisty ***** at the battery. My first fire came from trying to run a negative ground 8 track in a positive ground car using electrical tape as an insulator. If you hit a big bump a puff of smoke would come out from under the dash. Ha ha. Those were the days.

It's NOT the small gauge wire pulling too much current-it was either the wrong size wire or not fused correctly.

A fuse's job is to blow way BEFORE the wire melts- see chart below

There are dozens of post just on the C3 section where somebody connected the jumper cables with polarity reversed or battery cable reversed- the battery fuse would have saved several hour of replacing fusible links and/or smoked wires perhaps even a towing bill.

For LESS than $40- including a spare fuse - I can NOT see why you are not a fan- cheap insurance.

Richard

Yeah, you are right. It isn't a bad idea to have the fuse and a cut-off. My advice probably needs to be ignored. I tend to wire things up incorrectly first and I don't trust my work so the cut-off helps me sleep at night

HA-It's all good. I can't tell you the number of times I have accidentally swapped polarity... thank god most of the time smoke didn't come out!!! As I found the smoke is really hard to put back in.

I still remember the first time- my very first car- Triumph TR4- it had positive ground system and a negative ground radio did not work!!! Neither did those aftermarket horns- some good lessons!!!

Stuff happens- a $9 fuse is MUCH cheaper than your deductible!!

I had a similar issue with a Bugeye Sprite, hung my AM-FM 8-track under the dash off a block of wood. 8-tracks played great so I decided to have some radio too and plugged in an antenna. Turned on the radio and poof, the dreaded smoke monster appeared, like a jerk reached under and grabbed the antenna wire to pull it out of the back of the radio...man did that hurt...

Richard, where did you get that? Never can have too much insurance when it comes to battery protection...
