GEARWRENCH Short Circuit Detector is safe, portable tank fills and pressurizes standard and power brake systems. Operates from hand-pump pressure, eliminating the need for an air compressor. Only a few pumps are needed to build pressure to 10-15 PSI; excessive pressure cannot build up.
- Locates short circuits in 6 and 12-volt systems right through upholstery, body panels and metal door posts
- Brake bleeder pointer not included
- Use only with DOT 2, 3, 4, and 5 brake fluids
- Easy to wipe clean
