A friend got me a Rally Heater Fan (Link) since my defrosters don't work too well (haven't troubleshot that yet).

First, does anyone have any faith in an item such as this? If it's a waste of money, I'll just return it and thank them for the thought.

Second, and the main reason for the post - what is the amperage/voltage available in a stock 1992 hatch cigarette lighter? The heater says it needs 12V/20A, and I don't want to blow anything if I decide to use it.

Any help is much appreciated

Check the rating of the fuse for the cig lighter.

Cheers

- Mon Dec 20, 2010 1:43 am #228831 I gave the fuse box a look-see today, and the cigarette lighter and radio are on the same line, which is rated for 15A.

Without knowing much about the whole electrical process, I would suppose that if the defroster draws a full 20A while running (and my radio is on) that I stand a fair chance of blowing the fuse? Or is there any kind of headroom, so to speak, where I could get away with a supposed 20A draw on a 15A line?

I really need to start learning more about wiring...
