IMPORTANT SAFETY

INFORMATION

Install only on 12 VDC, negative ground 1.

vehicles.

Make sure that bracket and posts are unbent 2.

before connecting.

Verify that there are no short circuits before 3.

reconnecting. Check for loose strands of

wire, in addition to direct contact with ground-

ed components. Use a multimeter with a

continuity function to help verify that there

are no shorts to ground. When reconnect-

ing, be prepared to disconnect battery again

immediately in the event that an unexpected

short circuit causes sparking.

Turn off car engine and set emergency brake 4.

before installing.

Do not place tubing near any hot exhaust 5.

system components during installation.

INSTALLATION INSTRUCTIONS

Read the ENTIRE IMPORTANT

SAFETY INFORMATION section at the

beginning of this document including

all text under subheadings therein

before set up or use of this product.

Select a position on the dash for

mounting the Gauge Set. Drill 7/8” hole

in rewall and insert bulb tube and tting

through hole. Use holes in Gauge Set

Frame to mount the Set on dash.

Follow the specic instructions listed

below for installing each Gauge.

Oil Pressure Gauge

Remove oil light sender from the side of the 1.

engine block and disconnect the wire from

the indicating light on the dashboard.

Connect the coiled end of the tubing to the 2.

engine block (where the oil light sender

was removed) and the other end to the Oil

Pressure Gauge. Use plumber’s putty (not

included) to prevent any high pressure leaks.

See Figure 1, below.

To install Oil Pressure Gauge with function-4.

ing indicator light, insert bushing, nipple and

“T” tting (not included) in place of present oil

light sending unit on side of the engine block.

Connect the tubing to one side of the “T” 5.

tting and the other end to the Oil Pressure

Gauge. Then connect oil light sender to the

other side of the “T” tting.

Ammeter Gauge

NOTE:1. To install Ammeter correctly, make

sure that all added wiring is the same gauge

(or larger) as the wiring found on the car

(typically #12 or #10 AWG).

WARNING! Break existing connection and

mount Ammeter in series. Do not connect

between the heavy wires that run from the

battery and to the starter.

Proper connection will insure that any current

drains that exceed the alternator/generator

charging rate will be indicated as negative (-)

discharge on the Gauge.

Any alternator/generator charging current

output that exceeds the total battery current

drain will be indicated as positive (+) charge

on the Gauge

WARNING!2. Do not connect wires between

the brass hex nuts and washers at back of

the Gauge Set case. Doing so can lead to

loose connections and erratic operation.

In cars with magnetic starter switches (Ford, 3.

Chrysler) refer to Figure 2 (below) during the

following steps:

A.) Mount Ammeter where desired and route

the wires from Ammeter through the re

wall and to the magnetic starter switch.

B.) At the large solenoid terminal, disconnect

all wiring EXCEPT for the heavy battery

cable.

C.) Gather all disconnected wires and group

together using a nut and bolt.

D.) Connect one Ammeter wire to the group

of wires and insulate to prevent wires from

touching chassis, body or engine of car.

E.) Connect other Ammeter lead wire to mag-

netic starter switch terminal, where the

heavy battery cable connects. (This is the

same terminal where wires were removed

in step “b”).

F.) Keeping the engine off, turn headlights on

and observe the direction of the Ammeter

needle movement. It should point to the

left or “-” (discharge). If it points to the right

or “+” (charge), reverse the position of

wires at rear of Ammeter.

G.) Once proper indication is achieved on

Gauge, securely tighten all connections.

Make sure no parts of any exposed wire

conductors touch any grounded part of

the car.

In cars with a separate mounted junction 4.

terminal or a horn relay (such as GM) refer to

Figure 3 (below) during the following steps:

A.) Follow Step A on previous page.

B.) Disconnect the wire running from the hot

battery post to horn relay or junction ter-

minal (usually black).

C.) Connect one Ammeter wire to the termi-

nal post where the hot lead was just

removed.

D.) Connect the other Ammeter lead to the

hot wire disconnected in Step C. Insulate

wire from any ground contact.

E.) Follow Steps F and G, above.

In cars with the solenoid mounted directly on 5.

the starter (such as Chrysler and most inde-

pendent models) refer to Figure 4 (below)

during the following steps:

A.) Follow Step A on previous page.

B.) Disconnect the smaller wire (red) from the

solenoid terminal where the heavy bat-

tery cable is terminated.

C.) Connect one Ammeter lead to the wire

just removed from the solenoid batter

terminal. Insulate the joint from any

ground contact.

D.) Connect the other Ammeter lead to the

solenoid battery terminal post.

E.) Follow Steps F and G, on previous page.

Water Temperature Gauge

Locate suitable opening in engine block to 1.

reach the cooling system water or locate the

presently installed water temperature sender.

Inset bulb on end of tube into the hole and 2.

screw tting on tube into the hole until bulb is

held securely in place. See Figure 5, above.

The tube tting should t most cars. Use 3.

adaptors (included) if they do not. If adap-

tors do not properly t, check with vehicle

dealership parts and services center for cor-

rect adaptor.

Illuminating Instructions For All Gauges

To have Gauge Set lights operate off the 1.

same switch as the dashboard light, splice

the wire from the lamp bulb socket into any

wire presently used for lighting instrument

panel. Tape to insulate.

WARNING!2. Be sure that mounting panel

is electrically grounded to chassis of car to

ensure steady gauge indications and light

intensity.

To connect Gauge Set to 6V system, remove 3.

the 12V bulbs and replace with 6V bulbs (not

included.)
