I assembled both boards in the kit and and applied 13.5 VDC. With inputs leads shorted together and J1 jumpered I get all LEDs fully on. With J1 not jumpered I get the lowest green LED slightly on and the red LED fully on. I get the same exact result if I remove IC1 and power up the module.
Can someone post an image of the solder side of the pcb so I can visually look for my error? Can someone post voltages at various reference points to look for based on the 13.5VDC input?
Looking forward to trying to troubleshoot this error as an additional step in my first kit experience.
Most likely one or more assembly errors.
Sorry, this forum does not allow picture uploads
If you can provide LINKS (e.g. by using a free online picture base) to HI-RES and SHARP pics of your assembly (both solder- and component side)
then we can take a look and provide some feedback.
Here is a Picasa share with 2 photos - front and back sides.
ZD1 and D3 are swapped and there are numerous solderings that might require some re-work.
Please check this.
Swapped ZD1 and D3 and it fixed it. I couldn’t tell the diff between the 2 parts and just generalized the appearance of D1 and D2 and D3…
Thank you.
