Merc 496 Questions - Electricals
Good Monday all.
New to me Merc 496s are installed and were running great. Went on 2 week business trip and now Port motor does nothing when I turn the key....no click, no fuel pump...squat! It acts like the "Breaker" on the front of the motor has popped but when I push on it - there is no reset.
While gone there was rain and battery got down to 75% per my smart charger. Each motor is connected to it's own bilge pump (with an in-line fuse). Recharged battery to 12.5 when I returned. Also have 2 bilges connected to house battery bank which solar keeps topped off.
Battery at 12.5v
12.5 at starter and both sides of starter fuse.
Ground wire from battery replaced and "roughed up" where it touches block.
Replaced terminators on positive starter wire from battery as well.
Batteries are a two years old - sealed deep cycles. Are the 496s super sensitive to battery type or something?
Thanks for suggestions!

The 496s are sensitive to voltage, not neccessarily battery type. They don't like low voltage.

Power going into your ign switch ? Is there power going out when key is turned to on and start ?

Thanks for the suggestions Gents! I will check tonight .... as mentioned I didnt use it for 2 weeks and batteries did drop and get recharged. I should have thought of the purple wire and ignition switch itself (ass- oomed)
