MEP-003a Charging System - Higher Than Normal

[peapvp]

The Triplet Model 60 Meter here has a switch. V-mA / 2 and V-A-Ohm



The way this works is as follows:

you select the range you want to measure.

in our case @ckesey selected 100VAC

The black top scale above mirror is the scale we would read which is either

0 to 10 or 0 to 5

since we selected the 100V range, the indicated voltage has to be multiplied by 10 for a maximum reading at scale end of 10 x 10 =100

this is for the range switch set to

V-Ohm-mA

If we set range switch to V-mA / 2 then the voltage range is 100V / 2 = 50V
and we would use the numbers 0 to 5 on the black scale above mirror
so the scale shows 3.5 x 10 =35 VAC

So, it’s 35VAC and stator is good

That's great news. I'm going to hook up my new rectifer and see what DC charging voltage I get.

 

[ckesey]

DC Charging voltage looks to peak around 31.6v DC. Again seems high but while watching it on DMM it goes between 30.0v and 31.6. I'm letting it run for at least and hour and going to check the voltage periodically.

What does the DC charging meter show on front panel and are you testing on the battery terminals?

 

[ckesey]

The meter on the front panel shows in the green and occasionally bounces back and forth across the green/red line on the right side.

No I'm testing at the connection terminals and not the battery posts themselves.

You need to test / measure on the battery terminals

@ckesey

This is the wiring diagram in the -34 manual for the alternator



Are you measuring the 30V to 31V on TB6-1 and TB6-2?

Please clarify! Thanks

The -34 manual shows on how to test the A5 Unit after the Stator has been tested in the -12 Manual ( 30VAC to 35VAC)

Charging Test gp to pdf page 112

To correctly test A5 you will need a 12 Ohm 200W Power Resistor
