5.
Choose a wire size from the table in Dia- gram
3 that is a large enough gauge (larger
size wire has a smaller gauge number) to handle the maximum rated output of your vehicle’
s alternator/generator
. Obtain two
lengths of this size wire that are each long enough to go from the location that was cho- sen in Step 3, to the ammeter
’s
mounting
location at the dashboard. Attach closed-eyed type connectors (Diagram 4), to each end of both wires.
6
.
At the location you chose in Step 3, discon-
nect all the wires at the connection except the wire going to the battery
.
7
.
Connect an end of one of the wires you ob-
tained in Step 5 to all the wires you discon- nected in Step 6.
8
.
Connect an end of the remaining wire from
Step 5 to the connection in Step 6 that still has the battery wire attached to it.
9
.
If your system matches Drawings 2, 3, or 6,
connect the wire you disconnected in Step 4 to the wires already connected in Step 7. Use an additional piece of similar sized wire to join these wires, if necessary
.
10.
Insulate all connections and use a suitable method to fasten down the wires in Steps 7 and 9.
11
.
Route the two ammeter wires to the mount- ing location for the ammeter
. Insulate the
opening in the firewall they pass through.
12.
Mount the gauge and attach the remaining end of the wire from Step 7 to the ammeter connection post marked with a “+”. Follow the sequence of washer-wire-nut shown in Diagram 4.

.Attach the remaining end of the wire from
Step
8 to the ammeter connection post
marked with a “–” sign, again following Dia- gram 4.
14.
Reconnect the battery ground cable. As you do, watch for sparks and check if the wiring you worked with is getting warm. If either con- dition is noted, IMMEDIA
TEL
Y disconnect the
battery ground cable and read the

.
If, when you reconnected the battery ground
cable, you noticed sparks or any of the wiring getting warm, check that all connections are properly located, and insulated from ground- ing.

.
With the vehicle not running and the battery
reconnected, turn on the headlights’ high beam and observe the ammeter
. The gauge
should show a drain (–) condition. If a charge (+) condition is shown, reverse the wires on the “+” and “–” posts on the back of the am- meter
. If the ammeter shows no change, the
circuit from Ignition/Accessory (I) has not been properly included in the connections to the “+” side of the gauge.
