Yeah the cheap meters with the 10A socket will be unfused. The lower current range (typically 200mA or 400mA) should be fused. Quality meters like my Fluke 179 though do have fuses for both 400mA and 10A current terminals.

If you have a cheapo meter make sure you get your wiring right if you're using the 10A range. Worst case in a car though should be blowing one of its fuses if you thoroughly stuff things up.

Also you should be able to buy one of these cheap digital meters which is handy for other things very cheaply. Sub $15 should be easy.
