A buddy has a 150 HP in line 6 cyl diesel
with 'CHRYSLER MARINE' on the valve cover.
We are trying to locate the tach sender.
The tack signal doesn't seem to come from
the alenator, and after searching all
afternoon, I couldn't find any transducers
on the bell housing or the main pulley.

Anyone have any ideas?

Thanks
Mike

are you sure it doesn't run from the injector pump?


Tim

I didn't see any wires connected to the injector pump.
Any idea were to look on the pump?

Thanks for the reply

Mike

Wow mike,
I don't know. most usualy places for a tach lead is fromt he pump
electric sensing, or mechanical (Would look like a speedometer cable
screwed onto the end of the injector pump), the "W" (stator output)
terminal on the alternator
or some type of a crank positioning sensor either on the flywheel,
harmonic Balancer (front of crank) or camshaft housing.

This is most unusual.

Tim

Tim,
I haven't found it at any of those places.
We are looking for an old manual on the internet.
Mayby that will help.

I had four of theses tied to surface drives in my Starliner. Gotta
love those surface drives.

Mike, this is a really stupid question, but when you say you're trying
to find the tach lead, are you trying to install a tach where one
wasn't before?

or trying to repair the tach thats already on the boat?

if this is a new engine, it probably doesn't have one, and must be
supplied by the tach mfj.

Tim

Tim,
Not stupid at all.
The boat has two engines, the port side tach is working fine.
I can't find the sender on that one either.
By buddy says that both were working ok, then the starboard started
working intermittently.
