In Reply to: OBC and Tach posted by Nicholas on April 02, 2000 at 16:41:41:
The tach is fed through the S.I. board, so an S.I. board problem can make the tach inop. Does your OBC not light up, or not function at all? My OBC continued to function after the S.I. board wiped out, but the tach quit. I think it's possible to lose some OBC funtions related to fuel consumption if the S.I. board quits, but I'm not absolutely sure about that. If the OBC is not lighting up, then you probably need the $20 light bulb. Hope this helps.
