Re: Zamp zs30a controller flashing red
Chris, what is the voltage coming out of the controller?
You can rule out a separator issue in a few ways. Most likely it's a bi-directional Surepower.
>>>Check voltage on both sides of the separator to ground. One side will usually be different if it's open.
>>>Plug in the solar and see if the voltage jumps up on one of the lugs. That will tell you if the solar is working or not.
>>>Disconnect the solar and start the engine. Again, the voltage should jump up on one terminal. That way you'll know the separator is seeing a charge voltage.
In most cases the separator should close and when it does the voltage on both terminal sides should be the same. If it doesn't close there could be a problem with it. If you start the engine you can pull the separators ground wire off the ground strip and touch it on and off the strip or lug it's normally grounded to. This should cause the separator to operate and you'll hear it click open and closed. Sometimes they stick open or closed and a light rap on the solenoid might free it up. Also I've had dirty contacts cause a problem and the rapid open and closing might clear the problem.
But I'm having some issues with what you've posted. I don't understand why the house system is going dead in the first place. Hopefully your solar is able to keep up with the load. The solar is usually hooked to the house side of the separator so even if the separator is open the system should be getting charged. In any case, the engine should be pumping up the house battery. Perhaps you have more than one problem. If the solar is hooked to the starting side of the separator that would be a different story and an open separator would not allow any charge. Also if the separator is stuck open and your solar can't keep up with the load, then the battery would also slowly loose its state of charge even if itís hooked up to the house side. This can happen with a short or battery going bad. In a bad battery situation the separator usually closes when the engine is started and the alternator charging begins, but as soon as the motor is shut off the battery quickly dies and the separator quickly opens to protect the starting system. In the case of a completely dead house battery that will not take any charge it's possible the separator will never close.
Your main goal should be to get the house battery fully charged by running the engine and making sure the separator closes without the solar and go from there. Then make sure the solar is working. After a long charge the house battery may be warm but if itís hot the battery is probably going bad. As a side note you never mentioned the shore charger. You donít have that?
Post back what you find.
