Enhance Power Management Efficiency with Wirthco 0303.1233 30200 Battery Doctor Roundtapper Kit Review

I have an old car that still uses glass fuses. I needed a way to plug in my new stereo and this fuse allowed me to do just that and keep it looking clean.

Easy to mount on an old glass fuse box instead of rewiring. In this case a 1971 Ford F-100 has a total of 5 fuses in the original fuse box.

Lifeguard in an old car that still uses round glass fuses. I thought I could find them at any auto parts store but not anymore.

They may seem a little overpriced for what you get, but they do the job of adding an accessory without cutting into your car's wiring. It's a bit difficult to get them into the fuse holder when they are around the fuse as they are quite snug.

Works exactly as it should! I used them to connect sensors to my 1970 F100. It was a bit tight around the glass fuses in my fuse box but popped out and now my sensors are working. Will definitely buy again!

I used these on my '59 Bel Air to hook up the circuits to some of the modern conveniences I've added. They are very easy to install and save you the hassle of breaking cables. Just make sure you install them on the right side of the fuse!

The problem with some of the other reviews is that they sounded like they expected this product to be magic. They add a thin piece of metal to either side of the glass fuse (which is designed to fit snugly on its own). It will be a tight fit. I ended up breaking 2 glass fuses during installation, but fuses are cheap and it turned out to be MUCH better than cutting/soldering a 50 year old wiring harness.
