I have a fuse holder, currently with a 5A blade fuse, plugged into the "accessory" tap/port on the interior fuse box. Now connected to this fuse holder is my PLX AFR gauge, my V1 radar detector, and some heated seats. I need to confirm, but each item may have its own fuse before coming together to the 5A fuse holder going into the tap -- hopefully the configuration makes sense.

Everything works fine, but usually when I turn on the passenger heated seat (can't recall if the driver's has to be on too), the 5A fuse pops.

How should I remedy this? I can't simply add a bigger fuse (say 10A) at the fuse holder without any cause for concern can I?

 

It depends on the size of the wire and what kind of amperage the heated seats draw. I'm sure they're pulling more than 5 amps. You should run them on their own circuit, either right from the battery with a fuse next to the connector, or off a higher amperage feed from the fuse box.

 

^ I agree!

 

I couldn't figure out the amperage of the heated seats, so any idea on what higher amperage feed from the fuse box I can or should use?

Thanks for the input guys!

 

Do you not realize the problem with your question?

Who makes the seat heaters?

 

No

I believe these are the ones: http://www.seatheater-heatedseats.co...OVMTC=advanced

 

your heated seats are drawing more than 5A. You could use a 10A fuse (for all devices) and see if that works. If the fuse still pops, you should run a wire from the battery (with a fuse at the battery) and then relay it into the ignition lead.

 

Each seat will draw a max. of 5A. You need a 10A circuit or better yet, 15A for all those devices if you insist on running them on the same circuit.

 

Any reason(s) why I wouldn't want to run them on the same circuit?

Thanks for the input fellas!

 

If the circuit you were using originally used a 5A fuse, the wiring supplying power to that location uses a sufficient gauge to deliver enough juice for 5A of current. If you use a different fuse, the resistance of the wiring could potentially generate enough heat (under load) to melt the insulation on that wire, create a short, and start a fire. Granted, that is a worst case scenario... but I wouldn't want to chance it if it were my car. If it were me, and I was installing an aftermarket seat heater, I would run a new power cable from the battery to an aftermarket fuse panel where I could use whatever gauge of power supply wire I wanted, with whatever size fuse I wanted.
