Amp hour meter wire run...
Will the length of the wire run to an amp hour meter affect the accuracy?

This is another good reason to run your SHUNT TYPE sample in the NEGATIVE side of the battery circuit.
Otherwise you will a HOT 12VDC potential on the DC sample wiring routing back to your meter panel which could easily short out to frame ground and burn the whole length of the wiring back to the battery source.
The USE of the TRANSFORMER (HALL EFFECT) type DC current sample is a much better method to monitor your high currents but they are expensive to purchase.
SURE ELECTRONICS EBAY CHINA had a great $30 purchase for this years back but are no longer available unless you want to shell out over $800 or so... With this unit you just run your battery cable thru the opening and only small low voltage-low current sample signals are sent to the meter panel. No HAZARD potential present...
