Tie off any excess cable under the instrument panel. Be sure these cables do not obstruct the freedom of
travel of any controls.
12. Hook Up Connecting Wires:
Connect the red wire in the Connecting Wire Harness to the 12 or 24 volt bus via a 1 amp fuse or circuit
breaker (see the Wiring Diagram at the back of this manual). Connect the black wire to ground. Connect the
white/brown to the 12V bus (leave it open for a 24V system). Connect the white/red wire to the 24V bus
(connect it to ground for a 12V system). Connect the white/orange wire to the Panel Light Rheostat.
Tie off any excess cables under the instrument panel. Be sure these cables do not obstruct the freedom of
travel of any controls.
13. Instrument Installation:
Install the instrument from behind the instrument panel using 6 x 32 screws supplied in the accessory kit.
DO NOT USE SCREWS LONGER THAN 1/2".
If this instrument is to be mounted directly under a speaker you will need to install a magnetic shield. This
is a U shaped piece of steel sheet metal. Contact E.I. Inc. for details.
Connect all the Circular Connectors to the Smart Analyzer in the following manner:
A) Push the two mating connectors together and twist them until they snap into position.
B) Turn the locking ring on the instrument connector clockwise (1 1/2 turns) until it locks into posi-
tion.
14. System Ground Test:
A) Turn the master switch on and look for a near ambient temperature reading on each channel. If the
instrument does not power-up (display a reading), check the power and ground leads (red and black leads)
for an open, loose or poor connection.
If you suspect any channel is not receiving a signal remove the probe from the engine (leaving it connected
to the Extension Cable) and apply a temperature to it. Look for an increase in reading on the display for that
channel. Check the other channels for an increase in reading. You may have connected the probe to the
