Problem I am trying to resolve is after moving trim the reading floats around on mercmoniter before finally settling on a #. It may take 5 seconds other times 20 seconds for it to finally decide where it wants to read at. It may be at 5.2 bump trim up and it up to 5.1, bump it again and we are at 6.1? When trimming all the way down sometimes It lands on 0 sometimes 0.4 or 0.2 It doesn't get to far off track but definitely not consistent.
1- verified I have digital 3 wire sender.
2- I have calibrated trim multiple times
3 took 3 wire bullet connectors apart, cleaned and added dielectric grease
4-removed sender to look for broken unusual parts.
5- looked wiring over for cuts and abrasions
I have looked back through previous threads stating check ground at swivel bracket. Exactly where is this located? Looked 'all over port side. All grounds appear to be fine. Anyone have a pic of where it is? Is their a way to test sender ? Thanks
