IMO the power probe kicks arse
*test light with a 20' cord
*& another 20' extension cord for a total of 40'+
*positive and negative polarity at the flip of a switch
*continuity tester
*2 LED headlights to see what im doing
*sound to tell me which way or what its doing
*built in circuit breaker
* flashing red orange or green light to indicate polarity and alternating current
**and a accessory to send a radio wave down a wire to use with a receiver to find broken wires without even looking or touching them(this I dont have yet)
+no jumper wires needed
+check truck & trailer from one spot
+not wondering if its grounded
+able to power up a window or a seat with out a bunch of crap
+battery or cig lighter powered
think about it on the simplest thing a 1157 light bulb & socket in the time it takes to locate a jumper wire and hook it up ive already tested the bulb and socket and ready to go back tracking up the system
I bought it because my wifes brake light went out and the reverse were out too and could NOT find the cause all circuits were clear it wound up being a wire that went to the A/C & a transmission plug on the same circuit (all factory) that was never hooked up?? found the problem in less than 2 hours badda bing it paid for its self Vs. taking it to a shop
