Full Version: 25Amp Battery Fuse Melted

About a year ago a member here sold a battery fuse kit (Spoke?) Never thought I'd use it but it looked cool.

Started the teener tonight and after a minuted it went Dead Instantly! Knew it was electrical and since I'd recently installed a tach, decided to check the wires. Looked OK. and the dash fused were ok too.

Checked the battery fused and found a blown 25 amp fuse. When I think of what might have melted without that fuse................... headbang.gif

As soon as the butterfly horn was off, I see a cut horn wire. The DAPO installed this and I have been to lazy to wire it right.

Pulled off the horn wire, installed a new fuse, and took her for a spin! With Tim's new LED dash lights, I love driving after dark.

So,,,fuse the battery and let Tim do your dash.

Not me although the fuse is a good idea. There are several non-fused electrical items on the car and like you said, if your fuse wasn't there you'd be looking at smoked wires.

Porsche seems to have a long history of questionable electrical items. My '84 Carrera Targa needed to have 5 additional wires fused as the factory didn't have any (though they did eventually add some to later models).

A fuse or circuit breaker in the circuits fed off the battery would be a nice added level of protection for the wiring.

Tom made those. I've got one on my '76. Damned good idea to have one. Many folks don't know that they have unfused HOT wires running up the tunnel. Glad yours saved your butt. I haven't needed mine yet but it is cheap insurance. beerchug.gif

agree.gif I have one on my car and once fried one of the fuses when I hooked the yellow starter wire to the wrong connector. Very happy I didn't have a melted wire and ignition switch. Everyone should fuse all the wires on the battery except the large cable that runs to the starter.

Does Tom have a thread in the member-vendor section for this?

I put this in a few years back from a post someone put out there.
I bought all of the components from Dell City

We'll be doing an engine panel on Doug's 6 conversion. I'm thinking circuit breakers that you need to reset. So you know you have an issue.
Might get a head start on the design when Matt and I do the new snorkel in his car. I think every car should have one.

Here's my 1 in 4 out fuse block, think I got it off E-bay or Amazon can't remember now.
Will mount where out of direct rain exposure but easy to see fuses.

No. He only offered the kits once. IIRC, the response was small but he might make more if the interest is there. beerchug.gif

Always keep in mind there are a few unfused circuits on a 914. I too have added a fuse to the battery for unexpected shorts.

Sorry to hi-jack, I like this. Any further details of what is running from where and to.
Thanks.

I learned this lesson on a very early build 944. Turned the headlights on one night. One popped up, the other didn't. Smoke poured out from under the dash. Entire wiring harness going through the firewall was one big lump of goo. Found out later the headlight motors were unfused. All it took was a stalled motor to lead to a short to lead to China Syndrome.
