Really didn't mean to upset you. Just curious why you repeat so much of what has already been discussed. Your posts read like a self appointed expert.
I started this thread to discover if there was an alternative to the Bi-Directional brain box.
And look what I got.Tom/Barb wrote:

3. The Bi relay is a very LOW amp device. It just sends a 12 volt signal to the Big Boy solenoid to combine both battery banks to charge when it sees the 12 volt ignition wire/spade terminal get 12 volts
4. On Shore Power, IF the dc voltage goes OVER 13.1 volts and stays over, it will close that Big Boy to charge the CHASSIS battery bank. Conversly, if it sees OVER 13.1 from the chassis side it closes the Big Boy to charge the COACH batteries in transit.
5. How Many Bi relay's have you replaced? Other than corrosion, the other culprit would be HI dc amps inputed to the Bi relay box. Any Amps over 5 amps may destroy the Bi Relay box.
6. Here is a link for the Intellitec if you do not have the info.
7. Also, your batteries (or just 1 or 2) may be bad and causing the charging problem. I would have all 4 Coach batteries tested. If 1 is bad, replace all 4. Doug

Do you read others posts?

Here is what happened today..
Removed the Bi-Directional Isolator,
With jumper wires, I connected the ground post of the Isolator to the negative of the chassis battery
and the Ignition post to the positive side of the battery.
Then measure the voltage on the relay post 12.4.
Proving the Bi-Directional circuit works.
With the wires removed for the Bi-D I check each one for proper voltage/continuitity
Ignition wire shows 13.4 (battery voltage) with key on. 0 with key off.
Generator shows 12.8 with gen/set running.
Coach battery shows 13.4
Ground show no continuity to a known good ground.
repaired the connection to ground, I believe it is fixed.- 1. Intellitec Bi directional relay controllers do NOT fail very often. Most I have replaced was due to moisture/corrosion. Rarely do they just "fail".
2. I would suspect your chassis Alternator/Regulator is not up to full operation and is failing when you have the load of the Inverter in transit

No continuity to ground at the ground post of the Bi-Directional Isolator. Wire was on the post, and tight, found other end not connected to battery negative post.
Next test,, deplete the house batteries o 12 volts, by disconnecting the 50 amp cord, and running appliances.
start engine, and see if it will charge the house battery. pianotuna wrote:
If the load is so great why is the fuse not blowing on the circuit feeding the Bird device?
My OEM charging path included a 60 amp fuse which was hard to find. I replaced it with a 50 amp circuit breaker, and added a 2nd charging path with a 2nd auto reset breaker. I do have manual control over the charging circuits.
The Newmar has a 300 amp fuse in the Positive lead to the inverter. it is not blown, or the battery pack wouldn't charge or run anything.- After a period of Sunday evening to Tuesday morning, on the 50 amp plug, the chassis voltage is 13.4, coach batteries 13.4
The Inverter/charger is working, and the isolator relay is closed. (To charge both to the same voltage)
Ign terminal to ground reads 13.4 with key on, 0 with key off.
Next step. unplug the 50 amp cord see if the isolator relay opens. - As others have said the BIRD rarely fails,mine is good after 12 years and as a Former Rental it has had a lot of use.
I had the same problem, house battery not charging from the alternator,after checking all systems including the BIRD , I found that the continuous duty solenoid was the problem,not letting the Bird do what it is suppose to do. Have you checked that?
