Title: Omission in Eros assembly manual?
Post by: PKile on April 14, 2021, 08:30:06 AM

I am in the process of assembling my Eros 2.  On the shunt regulator board, there are two 220K ohm resistors at position R4, one end connected to the +reg pad on each corner of the board.  The assembly instructions state to leave the end of the lead untrimmed, leaving a pigtail on top of the board.  I don't see where these pigtails are used or trimmed in the subsequent instructions.  Am I missing something?
Thanks,
PKile

I think they're saying that they want you to not trim the lead that is joining the solder pads, but that you should trim the excess. If you look at the photo of the top of the board on page 49 you see that those leads are trimmed.

That's my interpretation.

Thanks oguinn...I questioned this because at first I had neglected to solder the leads at +reg, misinterpreting the instructions. I was getting 358 volts during the shunt regulator test.  Once I soldered the +reg pads, 220 volts and all LEDs were lit.

The leads of this resistor are trimmed in subsequent photos.  It's just important that the connection to Breg is made.
