Troubleshooting Tachometer - iboats Boating Forums
2014年3月28日 · A faulty rectifier wouldn't damage the tachometer, the tachometer simply wouldn't work. This is due to the fact that the tachometer operates off of the charging system and the rectifier converts AC voltage to DC voltage, enabling the charging system. A faulty rectifier disables the charging system, and the tachometer simply doesn't register.
Tachometer repair? | Boating Forum - iboats Boating Forums
2020年8月16日 · 1987 FourWinns 3.0 Mercruiser. My tach stopped working. It doesn't move at all when I turn on the key, or start the engine.

disassembling tachometer - iboats Boating Forums

Rectifier or Stator sends signal to Tachometer - Boating Forum

2009年4月23日 · Re: Tachometer OK just got the tach in the mail. As you can see in my original pic there are 4 round posts and 1 flat male post. The post that reads SIG also says Sync STBD. The post on the far right says Sync Port. What does the word Sync mean? The tach is being hooked up to a 1975 Merc 115.
Replacing a tachometer | Boating Forum - iboats Boating Forums
2009年8月22日 · The old tac was an OMC. The new tach I am planning to purchase (I don't know if the terminals are coded-they think it is an OMC- it is an older model but is new- meaning never used) has four terminals on the back to connect those wires. They claim that this is a 0-7000 RPM tachometer for use on 5-6-10 pulse outboards or pulse OMC Sea Drive engines.
