IGNITION TACHOMETER Model # GL10000, GL6000, GL8000 - All Colors Installation Instructions Wiring: NOTE: Cutout size - standard 3 3/8", bezel size 3 3/4" 1. Connect terminal marked SIG to the coil negative (-) on standard ignitions or to the tach terminal on electronic ignitions. 2. Connect terminal marked GND to a good engine ground. 3. Connect terminal marked 12V D.C. through an ON/OFF switch to the positive (+) terminal of a 12V battery. NOTE: In order to protect electrical wiring, fuse this connection. 4. Connect terminal marked LIGHT to 12 volt lighting source. NOTE: The pointer on your tachometer may not always rest at zero when the 12V power is off. This is normal. When the engine is started, the pointer will register the correct rpm. Engine Application Adjustments: This tachometer is factory set up to operate on 8 cylinder engines. For 4 and 6 cylinders engines, or 12 pole applications, it is necessary for you to make the proper adjustments. To do this, first remove the switch access cap on the back of the tachometer. Then, using a small pointed instrument, adjust the switches to match your application. APPLICATION

IGNITION TACH
IGNITION TACHOMETER Trouble Shooting STEP ONE(this usually solves the problem) - Before you do anything else, check for defective wiring or grounds, as this is the most common cause of failures. Inspect all wiring an terminals. Also, look for corroded or missing engine ground strap connections. STEP TWO - If pointer in receiver does not move when ignition switch is turned on, check to see that current is actually being carried from the ignition switch to the terminal ”I” on the receiver. Also, check to see that paint or corrosion does not prevent proper ground. If pointer still does not move, receiver is defective and must be replaced. STEP THREE - If receiver meter is not accurate with sender, check the receiver to be sure it is the correct OHM and VOLTAGE.
