Take your victories where you can :)Been looking for a short in the parking lamps on my 2004 Lincoln Town Car for like 6 weeks, probably spent 50 hours on it and replaced all kinds of parts, disconnected everything I could, etc. Anyway, this little sucker works by pulsing some current through the fuse slot that was blown. Hooked it up and started to look around, since I could disconnect everything except for the wiring to the headlights I started there. Looking at the connector to the headlights I swore I saw a little flicker of light, stared at it for a while and there it was again. Turns out the connectors in the connector were a little messed up and were intermittently touching each other, so it wasn't the gauge with the short finder that found it, but the capacitor sent the current and I visibly saw the hot spot where they were connecting. Problem solved, so it helped, just not how it was originally intended. Success story anyway.
