Hello,
I have gauges just not sure where exactly to hook them up to on the engine?
Oil gauge
Tach
Temp gauge
Any help?
I guess what I should say is I'm having trouble finding the exact spot the gauges get wired into on the engine. I don't know if there's a good diagram floating around?

One could ask why you didn't take pictures before the connections were disconnected but Brian can tell you where everything gets connected and help you get everything back together.
For the Lehman 120
Image 1, left: over temperature coolant alarm switch (Normally Open), activates alarm buzzer if coolant temperature is over about 200 F
Image 1, right: control panel coolant temperature gauge sender
Note: These are sometime reversed... Just flick one to ground (ie the block) and see if the gauge flickers or the alarm sounds to identify which is which
Image 2, left: oil pressure switch (Normally Open), activates alternator field and control panel gauges when engine is running with over about 10 psi oil pressure
Image 2, right upper: control panel oil pressure gauge sender
Image 2, right lower: low oil pressure alarm switch (Normally Closed), activates alarm buzzer if oil pressure is under about 10 psi
Note: coolant temperature gauge sender and oil pressure gauge sender should be "dual-station" for dual control panel boats and "single-station" for single control panel boats
On my boat, the Tachometer sender is an electronic "pulse type" that is on the Starboard side. It's hard to miss. Others have the tach set up on the alternator. I hope this helps.
Good stuff!!!!!!!!!!!!!For the Lehman 120

Small box with wires under the dash with holes to let the sound out. Normally within a foot of the keyswitch.I know this is an older thread - I just added all new gauges to my Albin 36 (Ford Lehman 120) - they are all working great, I do have a question as my "buzzer" is no longer functioning. The "low oil" alarm shoudl sound when the ignition is first turned on - but I am not getting that. I know where the two alarm senders are, I do not know where to find the Alarm relay or buzzer. Can anyone let me know where they are - or what they look like? I think I have a buzzer at both upper and lower stations - just not sure what I am looking for to trouble shoot.
