Q: tom lawrence wrote what kind of tester do you recommend any digital multimeter would be fine. if youre going to buy one you dont have to spend a lot of money but make sure you get one that takes normal aa aaa 9v batteries and not some hard-to-find specialty battery. the one i normally use on my vehicles cost me less than $20 iirc. i use one like this http//www.harborfreight.com/cpi/ctaf/displayitem.tafitemnumber=90899 cept mine is yellow. .
