A good schematic is worth its weight in gold for troubleshooting.
Good advice from all on the charging. It should be about 13.7 volts at 500
0 RPM below 15-18 amps draw.
I start by pulling all the circuit breakers on the ground. Measure the bat
voltage with a volt meter then turn on the master. Check which components
come on with the master ( those items not on CBs).
The master contactor can draw one amp. Look up your solenoid specs.
You need to use a VTVM or amp/ volt/ohm meter to check amp draw as you flip
on components.
Next=2C ensure your C or control voltage reads battery voltage. Look to se
e your alternator to panel or battery contact is secure.
Then start pushing in CBs to assess. Make a list of the components on each
of your CBs and their draw if you can. As an example=2C a turn and slip g
oing bad can be troublesome as the flag doesn't show but it is burning up a
mps instead of running at less than an amp.
In my opinion=2C the only way to check the health of your electrical system
in flight is with a volt and amp meter. You may want to invest in one.
Westach makes a nice combo instrument.
Keep plugging away you'll find the cause.

I get about 12.1 volts showing=2C
Pull all the CBs and you get a little more showing.
Now if you switch the MASTER SWITCH OFF=2C it fly's up to 13.1 volts.
I take it now that the Alternator has taken over the supply to the fuel pum

provided its turned ON.
So with the Master switch off and 13+ volts coming out it does not look lik
e being the Alternator or Rectifier=2C wear is the power going ?????
12v is not enough to maintain a full battery
Have bought a new battery =2Cbut the old one is as good as the new one=2C s
o it not the battery.
