Be nice to have a manual for the electrical system.

"I want a manual" is the number one asked question despite all of our attempts to advise everyone via posts/stickies/FAQ's etc that the manuals supplied with the boat are very generic and not boat model specific. If you want access to our detailed manuals then you will need to become a contributing member.
As for the tach yes corrosion is the usual culprit. On the back of the tach you will see a small dial. Spin the dial a few times then re-set it to "6 cyl". The slightest bit of corrosion due to dampness can affect them and this 'spinning the dial' sometimes corrects the problem. You can also pull off & re-attach the wiring connectors on the tach in the event there is a little corrosion there.
