![]() I installed a Li-bim (Lithium battery isolator manager) in place of the old isolator system components. I my case, the Lithium battery bank for solar panels is so large, it can pull way more energy/amps than the alternator can supply on a single steady charge so, something has to be installed to keep from cooking the alternator and that is an isolator of some sort. Herman, A # 4 stranded cable is rated at 70 amps and a # 2 is rated at 95 amps.The problem on the system can be over taxing the battery charging alternator on the engine while long distance driving. Going to a 1/0 wire would raise the current-carrying ability to 125 amps. A current that is way beyond what the the circuits should need.īeamer, could you post the size(s) of all the fuses in the primary 12 volt power panel in you Coach or just post the total current of all the fuses not including the main buss fuses. Then post the main fuse size(s) if by chance there a 2 main fuses. One could find a DC current prob at Lowes. They have them that can read 600 amps AC and 400 amps DC in the 40 to 50 dollar range if I remember. I have an Ideal # 61-768 and its been discontinued. The closest one would be the 61-746 at $ 69.00 from Amazon. Could be $100 to $140 more at some outlets. Man things have gone up since I got mine. Well, That might not be an option for you. Should you fined someone that has this type of meter, they can read the current flowing in the circuit. The total current draw through the Solenoid / Relay could lead you to an issue in a sub 12 volt power panel. Reading the voltage difference across the Solenoid / Relay. Low resistance equals lower heat (low power loose). High resistance equals High Heat ( High power loose) Bad relay contacts. Time to replace the relay, but in your case you have replaced the relay. Big difference, go back to the store, the one you got could be bad.īy chance could you attach a picture or 2 of the solenoid and the wiring around it ? So that is not the issue unless you got a bad one and that could be determined by just reading the voltage on the input and output. The real interesting item is, being plugged into shore power a charger is generally running at 30 to 40 amps.Intellitec’s Bi-Directional Isolator Relay Delay – Diesel #00-00839-000 That much heat means a lot of power going somewhere, and the where is the real issue. Intellitec’s Bi-Directional Isolator Relay Delay – Diesel offers a new approach to charging batteries in an RV which uses an alternator. Adding a small dash-mounted switch will allow emergency starts of diesel engines, requiring up to 800 amps of starter current. Unlike proper systems that only allowed charging the RV battery from the engine’s alternator, the Bi-Directional Isolator Relay Delay – Diesel chargers both batteries when either one is being charged. When the coach is being driven, both batteries will be charged from the engine’s alternator. When the coach is plugged into shore power, both batteries will be charged from the converter. ![]() If neither battery is being charged, the batteries are fully isolated. The controller also senses heavy loads on either battery to prevent the wrong battery from being inadvertently discharged. ![]() The unit is housed in a plastic enclosure for mounitng in an engine compartment. To connect the two batteries together under proper conditions, it operates in combination with an intermittent duty solenoid, similar to ones used as diesel starter solenoids. In order to use this type solenoid for continuous duty, the controller will engage it with full voltage and then reduce the coil voltage to approximately 4 volts to hold it in. #HEAVY DUTY BATTERY ISOLATOR RELAY TROMBELLA FULL# The Intellitec’s Bi-Directional Isolator Relay Delay – Diesel operates by sensing the voltages on both batteries. When either battery is being charged, the controller will close the isolator solenoid, connecting the two batteries together, charging them both. #HEAVY DUTY BATTERY ISOLATOR RELAY TROMBELLA FULL#Īnytime either battery voltage goes above 13.3 volts for approximately 5 seconds, the solenoid closes. ![]()
