NOTES related to Nevermore's engine wiring configuration:
- See page Q.2 right-hand side for the SCHEMATIC INSERT for Westerbeke 50 engine's starter and glow-plugs. This diagram replaces the INSERT on the left-side schematic. Nevermore has 4 glow-plugs, not a pre-heater, and has a starter with integral solenoid; the starter's "-" is grounded on the engine.
The 2 user-provided CktBrkrs (parts 45 & 46, discussed in written notes circle-B and circle-C), are located toward the back of the engine, and can be seen from the companionway area when viewed over the oil catch basin under the engine. The two reset buttons are visible, and the "10" and "40" amperage ratings are somewhat visible.
- The optional SPLITTER (part 44) is not installed. We believe that Nevermore's schematic can be read with a metal connection between terminals "A" and "1" on the splitter on the schematic.
- Tech Manual page V.11 Service Bulletin #87 discusses adding the optional splitter. To account for voltage drop across the splitter, it says to "connect regulator wire directly to alternator output rather than to the regulator terminals". (Thom can't make sense of this on the schematic without the Svc Bull 22Sep07).
- TODO: Per above note, (1) see if Svc Bull. #87 shows the "...regulator wire...", and (2) see if we need to make a NOTE that changes the wiring at the alternator to agree with NOT having the splitter installed.
- The fuel pressure switch mentioned in note circle-G is discussed in Tech Manual page V.15, Service Bulletin #94. It MAY discuss how to attach remotely located switches into the fuel-pressure fluid circuit.
- Written note circle-I isn't operative, since the control panel IS installed.
