Mounting the Panel
1. Select a suitable mounting location on or near the engine. The location
should provide easy access to the panel and provide unobstructed
viewing of the Swichgage instruments.
viewing of the Swichgage instruments.
2. The mounting location should avoid shock and vibration to the extent
possible. Generally, a location low on the engine is preferred. Avoid
mounting on top of the engine if possible. Shockmounts are
suggested where possible to dampen shock and vibration.

suggested where possible to dampen shock and vibration.
IMPORTANT: Use of improper shockmounts can accelerate the shock
and vibration effects. Consult the factory if you are in doubt.
NOTE: If shockmounts are used, it is suggested that a separate ground
wire be attached to the panel assembly and to the engine. This assures
electrical continuity between the Swichgage contacts and the battery
ground across the shockmounts (see mounting detail below).

tubing, install at least 12 in. (305 mm) flexible hose from the pres-
sure Swichgage instrument to the rigid tubing. This prevents damag-
ing vibration from reaching the Swichgage instrument.

NOTE: The orifice can be removed for cleaning.
3. Connect the pressure tubing to the pressure galley of the engine.
Generally this is at the oil filter housing. Use of non-hardening
thread sealant is recommended. Avoid droops or sink traps in
routing of the pressure line.

INSTALLATION INFORMATION
Description
Generally, pressure and temperature Swichgage
®
contacts are wired to a
central nerve center called a Magnetic Switch or Tattletale
®
annunciator.
This nerve center is essentially a relay and, when signaled by a
Swichgage contact operation, it either makes or breaks a circuit to oper-
ate an alarm or engine shutdown device. Various nerve centers are used
Swichgage contact operation, it either makes or breaks a circuit to oper-
ate an alarm or engine shutdown device. Various nerve centers are used
depending upon the operation to be performed, the type of electrical
power available and the type of alarm or shutdown device used.
Typical wiring diagrams for the popular Tattletale annunciators and magnet-
ic switches are included in this instructions. If a drawing of the specific
model number is enclosed, refer to that drawing for specific wiring.
