First of all.....This forrum is the best! I want to thank all of you for helping me out and everyone else on this board. You guys are a great way to learn how to fix the cheap way. I wish I could buy all of you helpful people a BEER!<br /><br />Back to my post. I just recently changed my voltage regulator on my 1989 225 Johnson and everything works great. The tach is now reading, but of course in the I changed the setting on the back of the tach and now I am not sure if I have it in the right spot. There are four knotches and I can't tell which is the correct spot. <br /><br />The tach has an elblum that looks sort of like a t-shirt (if this helps) with big sleeves. I thought I would shove that in there. Thanks for your help in advance.
