If you continue to get mixed results, acquire a clamp on meter that reads DC. Clamp it over any wire where you need a current measurement and remove doubt.

In preparation for my Lithium install, I did a wire trace of my Hawk electrical hook up and called Brenda (FWC) to confirm somethings. The 12v disconnect switch only removes the camper battery from the 12v circuit of the camper. The IOTA connects directly to the fuse buss and allows power to the 12v circuits even if the 12v switch is turn off. Because the IOTA first goes to bus then the battery, turning off the 12v switch, removes the battery from the buss and the IOTA.cdbrow1 said:Found another oddity this morning, which has me stumped.
I left the unit on the LiFePo charger overnight. In checking this morning I saw that both the truck and camper battery were at the same voltage (13.6V). The disconnect switch has been thrown so the camper battery is (supposedly) isolated from the truck but the truck battery should be at 12.6 votes max after sitting over night. The fact that both batteries are at the same voltage seems odd to me, especially when it is above the normal "resting" voltage.
I have verified that the system property isolates the camper battery so it does not deplete the truck battery in the past. Is it possible that the isolator (surepower 1314a) allows the camper battery to charge the truck battery? In reading the surepower documents it is not clear what happens when the house battery has more voltage than the truck battery. It does state that linking is possible but only manually - is would be automatic linking if the charge in the house battery exceeds the truck battery.
Anybody have any thoughts?
X2, topic is way over my head. May add the additional 80-watt panel. jdKILR0Y said:Thank God for my stock set-up with dual AGM batteries, gas fridge, and 100w portable solar panel.
Never have any issues (knock on wood! )
I do like the capacity of these lithiums and am interested in how the bugs get worked out!

At this point the Lithium is still a plug and play option - the only non stock thing involved is the Xantrax amp meter (which is a smaller version of the Trimeteric). I need to make a few phone calls to vendors and try to get a handle on what is really going on here. I am very confused when I see the truck battery volts climbing and the camper volts dropping after the engine is off. Perhaps I have a bad isolator or an installation issue.longhorn1 said:X2, topic is way over my head. May add the additional 80-watt panel. jd
Could the Separator be stuck in the closed position? Disconnect all connections to the Separator. Check for continuity between the truck battery post and the camper battery post. Should be open (no continuity).cdbrow1 said:Disconnected the wiring to the truck battery last night. I still showed a 0.5 amp power drain. The truck side terminal on the isolator showed the same voltage as the camper battery - even with the truck battery disconnected.
