**Wiring & Connections**
* contact surfaces of mechanical connections are cleaned and coated with moisture resisting sealant before being put together. no frayed or cracked insulation (check bilge and engine compartment)
* 12 Volt system leaks less than 5 mA of current (test) battery switch connections clean and sealed for each **on** position, voltage drop is less than 0.5 Volts in battery switch, while engine is cranking fuses have clean, tight, sealed contacts
* every electrical system is documented in diagrams or schematics
**contact surfaces of mechanical connections are clean and coated with moisture resisting sealant before being put together**
* Note: Sealant does not need to conduct electricity. When you force two clean and sealed metal surfaces together with enough pressure, high spots in the metals press against each other and force the sealant aside. In this way, metal-to-metal contacts occur all across a connection, with *doughnuts* of sealant surrounding each contact area. Use petroleum jelly (Vaseline), water resistant grease, or a specialty product such as Lanacote for sealant. When sealing light bulb bases, replaceable fuses and other friction connections, rock the connection back and forth a few times to create good metal to metal contact while squeezing the sealant aside. Applying sealant to the exterior of existing connections will help prevent deterioration but may not last long. By sealing the interior surfaces of a connection before you put it together, you get a long lasting barrier to the moist marine environment.
**conductors not kinked or bent sharply
Sharp bends will fatigue metal which eventually can cause fracturing. (Loss of electrical flow)

I had a simular problem on my 91'. It would only miss every now and then. After spending for a tuneup etc.
After being told it was probably a bad injector, it was acutally a bad connection, where someone had, had
the system apart before, causing a drop in amps, corrected that and also found loose ground connections.
it fixed the miss, and I have also not seen a low AC reading now for about two weeks. Bottom line correction
the ground probably fixed more than I had realized. The bad electrical connection on the injector setup
cleared the rest.

Now about electrical connections. I started my Cadi to go to lunch the other day and got a low
oil pressure warning. Panic. Started it twice again and it went away on third start. Also noted no
rise in the Oil Pressure indication when I had the warning. I then recalled that I had noticed the
oil pressure jumping a couple of bars over the past few months but nothing I considered serious.
Got under the car that night and removed and reinstalled the Oil Pressure sensor connector (no
small feat) a couple of times and all has been well since.
