P30 Step Van HELP!!

I see that Danny Boy as usual, has a sharp, less than helpful answer. (Must work for Microshit---while your answer was TECHNICALLY correct, it really wasn't very helpful.)


What you need is a "short finder", like this, available at any decent auto parts store



What this thing consists of is an auto - reset breaker that operates like a turn signal flasher. Some of them I believe, have a limiting resistor in series to limit excessive current. You hook it across the fuse holder (with fuse removed) and with the short "in progress" it clicks on / off

You can "wiggle" the wiring to uh............."encourage" the short.

The meter thing is sort of like a compass, IE it's a magnetized needle, and you move it along the harness. When you get to a high- current point, hopefully near the short, the needle will deflect wildly. If you move along the harness PAST the short, the needle tapers off to sometimes, nothing.

Sometimes you can also feel the harness for heating near the short.

Check anywhere the harness, or a wire, such as a socket wire lead, goes through a frame, near a sharp object, a clip, hole in the body, etc

(Some newer, more expensive short finders operate differently, more like a "toner" used in telco/ ethernet work. They work by sending a signal downstream of the blown fuse, and you then use a detector device to chase the shorted wire
