"All the electronics are connected to a fused circiut board under the dash. "
" It went off when i pulled the fuse to the electronics."
"Both units are plugged into circuit boards(one under the dash & one under the bow)."
" When the units are unplugged the test light still works until the fuse is pulled"
Trying to understand if the electronics are connected directly to the fuse panel, or as you stated, " a circuit board under the dash and one on the bow"?
