no jumps in reading the meter

how are you powering the display
mine is on all the time
it sounds the converter charge current is NOT going thru the sensor, but some parasitic load is being measured
where did you place the hall effect sensor ?
you might need to move it to a different location in the wiring, how many wires connect to the battery posts, and how many wires are going thru the sensor ( a picture would help)
what does the meter display, if you hitch up and start the engine but DON"T move
it works in either the Positive line or the negative wire, just flip the sensor the other way IF you change wires
do NOT use the battery disconnect switch, when using shore power
The hall effect sensor is in a weatherproof box mounted beside one of the 6 volt batteries on the A-frame. The positive wire from the battery goes through it.
3 wires come off of the positive battery terminal: the main battery wire; a wire powering the jack in front; a wire feeding the board on the meter in question.
A comment about interference reminded me that I recently replaced my tire pressure monitoring system. The new one came with a repeater for the tire sensors. It needed to be mounted toward the front of the trailer, and is weatherproof, so I mounted it to the weatherproof box I'm using for the meter components, and ran the repeater =/- wire into the box and connected to the wires I am using to power the meter components. It was the path of least resistance at the time. Do you think the repeater is messing with the meter?
