INSTALLATION INSTRUCTIONS

Installation
Read before installing:

THIS PAGE IS PRESENTED FOR INFORMATION ONLY. NOT RESPONSIBLE FOR FAULTY INSTALLATION OR YOU NOT CHECKING TO SEE IF IT IS RIGHT FOR YOUR VEHICLE. VERIFY INFORMATION GIVEN ON THIS PAGE.......

WARNING

Have your maximum alternator output tested. Choice of improper ammeter rating and/or wire size, and any

loose connections can cause dangerous overheating, which could lead to a fire in the vehicle. Ammeter and

wire should have a capacity of at least 10 amps more than your vehicle's maximum alternator output.


WIRE SIZE	MAX. AMP. RATING
12 10 8 6	25 40 65 95

PRECAUTIONS

1. Never ground either of the connections posts for the ammeter.

2. Always use a wire size that is rated to handle an electrical load equal to or greater than the manufacturer's specified output of your alternator/generator

3. Never connect the ammeter into the circuit between the battery and the starter/solenoid

4. Good electrical connections are important for maintaining gauge accuracy and avoid heat buildup in the wiring

INSTALLATION

As the many different vehicles that have been produced have minor differences in the routing and connection points of their charging systems, it is not possible to provide specific information for each vehicle. The eight drawings below cover the relevant connection points of virtually every charging system in modern vehicles. You will need to determine which drawing matches your system. If you have difficulty in locating any of these connection points refer to a wiring diagram in an owner/service manual or contact you local dealer/auto electrical repair shop for assistance.

The following connection points are represented in the drawings

B - Battery: the positive terminal

S - Starter/Solenoid: the main power wire to the battery (the largest wire)

A - Alternator/Generator: the main power wire to the battery (largest wire at alternator) and in Drawings 1 & 5, the wire from the ignition/accessories

I - Ignition/Accessory: the main power wire, which receives power regardless of ignition key position

Z - Junction: in Drawings 4 & 8, where "I" connects into the circuit

1. . Disconnect negative (-) battery cable. (Wear safety glasses.)

2. 10 GA wire or larger must be used

3. IMPORTANT: Verify that base nuts on both meter terminals are tight. Tighten base nuts prior to installing terminal lugs and wires. Connect ammeter as shown:

Example wiring of a typical Ammeter installation Consult vehicle

Mfr. for specific wiring details and safety considerations.

s CAUTION

DO NOT CONNECT THE AMMETER ACROSS THE BATTERY

4. IMPORTANT: Terminal lugs must be

BOTH crimped and soldered

4. IMPORTANT: Terminal lugs must be BOTH crimped and soldered to wire; star lockwashers must be used on both sides of terminal lugs.

5. Tighten terminal nuts to compress star lockwashers into terminal lugs.

6. Verify that none of the ammeter connections are to ground.

7. Install light in gauge and connect wire to instrument panel lighting

circuit or to any 12V source and connect a separate ground wire

between the center ground terminal and a good engine ground.

8. Reconnect negative (-) battery cable.

9. Leaving engine off, turn on lights. Indicator should read negative (-). If

it reads positive (+), disconnect neg. battery terminal and reverse the

wires on back of meter, then reconnect neg. battery terminal. Before

starting engine, double check that all connections are tight. After

starting engine, check wiring connections for hot spots. Be prepared to

shut engine off immediately if hot spots are detected.
