More batteries and new Univolt?

Greg, The meter itself draws .31 when the display is on. If you turn it off, it drops to .15-.16. Thats not much and obviously it has to power itself but I'd keep searching for a parasitic load if you are seeing .2. That is 200 mA with the 500 amp shunt The only other thing on the installation is to make sure the G1 and G2 connections are tight on the shunt.

I guess the sure way to check for a parasitic load is to pull the fuses out one at a time and see if I can isolate the mystery load.

Randy, You advise that the meter draws .31 when it is on. Is this the ".2 amps" I'm reading because my meter is on? What would be the best way to measure any mystery load if everything, including the meter is turned off?

Is the .2 amps an acceptable amout of loss if I can't track down the loss?

Greg,
Since you installed the 500 Amp shunt, .2 = 200 mA. 1000 mA = 1 Amp

From Bill Darden's Battery FAQ:
"Connect a 12-volt bulb across the positive and negative battery terminals to test the bulb and the battery. If it glows brightly, then remove the negative battery cable and connect the bulb in series between the negative battery cable terminal clamp and the negative battery terminal. If the bulb continues to glow brightly, then start removing fuses or connections to the positive battery post one-at-a-time until the offending electrical component is identified by the bulb dimming."
