The C-Charger series a product of extensive heat-chamber engineering and testing. The performance is far superior to comparable labels on the market Installation Instructions
Prior to starting this isolat or installation, start engine and run it at fast idle. Measure voltage at the battery terminal. It should be about 14 volts. After installation, recheck above to confirm the same voltage.
All tests to be taken with fully charged batteries.
- Disconnect ground/negative cable from battery.
- Mount Isolator in l ocation away from maximum engine heat and in a location that will let the Isolator receive maximum airflow.
- Remove all wires connected to the original alternator output post. Move these wires to the B#1 battery post on the isolator, if original factory is olator is used. If you are upgrading to a higher output alternator, tape off original output wire from original alternator. Consult wire size chart and install a new larger output wire from the system battery to the B#1 post of the isolator.
- Install new wire from alternator output post to the “Alt” post of the isolator. Make up a new #8 gauge minimum or refer to wire size chart for proper wire size based on alternator rating.
- Attach auxiliary battery to the B#2 auxiliary battery post of isolator. Again, r efer to wire size chart for proper wire size.
- If a circuit breaker is going to be used, it would be installed next to auxiliary battery. NO circuit breaker is to be installed from alternator to isolator or from isolator to main system battery.
- Connect all auxiliary loads to the auxiliary battery. For best results all batteries need to be of the same type construction.
- Reconnect the ground/negative cable to the original battery.
- Engine not runningB#1 terminal of isolator should read system battery voltage. B#2 should read auxiliary battery voltage. The “A” terminal should read 0 volts.
- Engine running and alternator chargingB#1, B#2 should read approximately the same voltage, which will be the voltage regulator setting or less. The “A” terminal should read .8 to 1 volt higher than the reading of B#1, B#2 terminals.
- For 12 - volt systems, the “A” p ost should read approximately 15 volts. The B#1 and B#2 posts should read 13.8 to 14.2 volts. If the “A” posts reads 13.8 to 14.2 volts, the regulator is sensing the alternator output rather than the main battery. This situation needs to be c orrected for proper charging
