hi all

my buddy has a BSD and he has to change the batteries every month. Any one have any ideas on the cause/fix?

Thanks

this is usually a shorted blocking diode. test the diodes around the battery looking for one shorted in both directions.

can you test diodes in circuit?

Quoted from busa32927:

can you test diodes in circuit?

in this case yes. Because there is nothing in parallel across it.

you cannot test a diode in circuit on something like a solenoid coil because of the being across the low resistance of the solenoid.

I had that too, with a Rottendog MPU. I just went with NVRAM and called it a day.

Any one know what common kind of lithium batteries are used? I took mine out to get a replacement and misplaced it. It was the size of a nickel and 4 numbers.
