Guidance in Replacing Senders and Gauges in Your Existing
Panel.
It is important to match the sender to the gauge and likewise
the gauge to the sender. Not all gauge manufacturers function
on the same variable resistance. A mismatched gauge or sender
will produce an inaccurate temp or pressure reading. If your
vessel has an upper and a lower operating station with 2 sets
of gauge panels per engine, then special dual station senders
are required. Please be careful to state this when ordering.
To order either a loose gauge or sender for an instrument
panel not supplied by TAD Inc. it is important to give us as
much information as possible, the brand name of the gauge and
the NPT (National Pipe Thread) size of the sender see chart
below, If you are uncertain and can not check your NPT size
it is recommended that you select the smaller NPT size. A
reducer bush may then be used to adapt to a larger NPT size
if required. Indicate if the sender has 1 or 2 terminals.
Ordering a Replacement Gauge:
The scale of the gauge is important. Example 0psi 80psi
(1bar -5bar) for the oil pressure and 100 deg. f 250 deg. f
(38c 120c) for the water temperature. Diameter of hole
gauge removed from. If we are not able to identify your old
unit we can usually supply you with an alternative new
matching gauge and sender. Some of the popular
manufacturers are: VDO Faria Datcon Stewart Warner
Teleflex AC (Not all currently available).
Ordering Alarm Switches:
When ordering alarm sensors these are referred to as
switches. (They make and brake contact sending a warning
signal to the alarm device) These switches are more
generically similar. The variation is usually in the setting
at which the contact is made and alarm will sound. In most
cases there are 2 switches on the engine one indicating high
water temp and the other, low oil pressure.
In order to supply a replacement alarm switch, we will need
to know location on engine and purpose of switch, the thread
size and # of terminals. See NPT thread size chart below.
Ordering Tachometers:
Most modern tachometers operate off of the AC connection on
the engines battery charging alternator. As the engine speed
increases and decreases it varies the AC output reading to
the tachometer. These units offer a stable reading, are
reliable and virtually maintenance free, unlike the old cable
drive units. It is however important to ensure correct
alternator belt tension is maintained. Belt slippage will
result in a low erratic reading. (Picture Typical Datcon
Tachometers ) Fits hole size 31/2
These
units will require a one-time calibration when
installed. This is normally done with the aid of a hand
held tachometer reading from the crankshaft pulley.
WIRING COLOR CODE CONNECTIONS
FOR TAD INC. PANEL

ORANGE #16
Alarms - Connect to low oil pressure alarm switch sensor
and link to high water temp alarm switch sensor. Both must
be linked to same orange wire.

Main Alternator Output Terminal to Battery/s - For
standard alternator, 65 Amp or less, connect to positive +
main large terminal on starter motor to main output terminal
of alternator. Read note below when utilizing a high output
alternator (over 65 Amp).
IMPORTANT FOR
HIGH OUTPUT ALTERNATOR (ABOVE 65 amps)
Customer should
supply and fit a larger wire from the output terminal on the
alternator to the battery/s directly or via main Positive
terminal on starter motor. Wire sized according to output and
length of wire. If the alternator is isolated ground then the
size of the ground wire should also be increased. Contact
alternator manufacturer for recommendations on wire size.
Standard # 10 Red wire in harness is only suitable for
standard 65 amp alternator.
IMPORTANT:
Using too undersized or incorrect wire could cause a fire
hazard.
