For sale bare boards for Delta Pulse/Sniffer XR-71

[chuubaba]

I already changed VD7, VD8, VD9.

i do not want to know what you change.

i asked you to measure the voltages.
you see yourself - NO POWER SUPPLY ON THE BOARD. ABSENT.
begin to fix the problem.

[chuubaba]

ok

[Andi68]

Check your Battery

[chuubaba]

Check your Battery

Battery is giving 12.12v
Andi i don't know how to diagnose voltage fault. I don't want to blindly poke the board with DMM

[Andi68]

Was the voltage measured during operation?

[chuubaba]

Was the voltage measured during operation?

yes i measured voltage on -E and +E during operation.(coil not connected)

All other please refrain from getting involved in helping Chuuby. This will only make things more confused.
Allow KT315 to assist him without distractions.

TOO MANY CHEFS IN THE KITCHEN SPOILS THE BROTH.

You may check in from time to time for some laughs, for when the magic smoke appears! Which I anticipate will be soon.

He should send the board to Kt ...

Thank you Andi but not possible.
Realizing how DIY is this forum and what "basic knowledge of electronics" implies this is my last project and purchase from the forum.

this is a forum DB and everybody has a right to bring a suggestion on the kitchen.
give a pic of your tester that you measure voltage.

measure voltage on terminal block, ON THE ITS SCREWS DIRECTLY.

The voltage here is 12 V DC.

Next i measured +E 0.17v DC.


Next i measured -E 0.07v DC.

Voltage on screws of terminal block.

i did not ask you to measure in other points. i am not interesting in a result of your stochastic wandering at pcb without any understanding of the schematic
and what you want to see there.

measure voltage on pic
