Yamaha 50 HP 4 Stroke cherp alarm is steady before starting.
The dual batteries were disconnected as well as the battery switch (1, 2, All, Off) for a couple of months. When re-connected to battery source, the ignition cherp stays steady, no guages and engine runs. Motor is cold. This may be a wiring problem from when all batteries were disconnected and not wired correctly now. Any suggestions or a readable wiring diagram would be appreciated. It all worked correctly before disconnection was done. The guages are tach, gas guage and depth finder. Gas guage budges but does not read correctly, just barely above empty.
