At the BIRD there should be a GEN spade with a wire. DISCONNECT that GEN wire and the BIRD should allow bi directional charging as long as the Converter(Inverter/Charger) supply voltage is OVER 13.2 volts. Remember, BI directional when on Shore/Gen ONLY happens when the House charging system supplies over that 13.2 volts. Once the Charging goes to float(usually this is less than 13.1), the BIRD drops out the charge to the chassis side batteries. Doug
I doublechecked my files and went to Intellitec. They offer NO BIRD that has a Genset setting that I can find. IF your Monaco has such a system that is designed and installed by Monaco. I do not remember a charge system that had the Genset disengage the BI charging just on Genset. We sold and I seviced Monaco's from 1998 till they went under in 2008/09. They DID have a feature (optional on the models from Cayman/Diplomat/Knight and down the cost scale/standard on the higher lines) on the large main fuse board up front in the storage, there was an empty area in the center with a multi prong plug where you could buy from Monaco and install the Bi directional module that would charge the chassis when 120 voltage was available. Now, Monaco sent out a TSB over 10 years ago and this may be what you have---When the original wiring was done, IF you have an Inverter/Charger or a converter that had the bulk charge adapter, when the chassis engine was ON and the genset was ON and the Inverter/Charger went to BULK charge (over 14.1 volts) this caused the ALT light on the dash to come on. This was because the fault for the chassis Alt as set at 14.1 volts or over. The solution was to install a relay that was connected to the genset Hourmeter 12 volt positive thru a bosch relay that anytime the chassis engine was ON and the Genset was ON at the same time, the chassis Alternator did not charge the coach batteries, since the Inverter/Charger would be charging them. Once the Genset was turned off the bosch relay closed to allow the chassis Alt would charge the coach batteries. Doug
Doug, everything you say here is true except the statements in red. Intellitec makes the model 839 BIRD. The 839 has the gen lockout feature designed to prevent the interference you mention above. Monaco does not make a BIRD device.
The OP has a 2000 model The 839 was NOT available back then. MY post was for HIS model. Intellitec obviously developed the 839 after 2007/08. The Bosch relay system I mentioned was DESIGNED by Monaco for the problem I outlined. IF they had the 839 back then, that is what we would have installed. If you read the 839 instructions, it specifically states that the Gen spade and design is exactly for the ATL fail light when Gen and Engine running at the same time. So, that is how the OEM's have addressed the Alt fail light problem. This problem can happen on Roadmaster/Ford/Frtliner chassis systems. Workhorse never had the problem. Doug
