Instrument bulb holder help

Hi All. I need some help with this bulb holder. I tried to find a new one but no luck. All my lights work accept the oil light. On the attached photo that is the second socket from the bottom. Is the post to the right of it the ground side and the post to the left the hot? Can I solder a wire from each post and run the ends down into the light socket and then push the socket in? Thanks in advance

Are you sure it's not the sending unit that's at fault? Easy test, disconnect the wire from the sender and ground it to the case. The bulb holder is available from Mark Huggett in Germany for $95.

Yea it's the socket. The little copper tabs are torn off. I tried to solder the right side but no go. The tab is pretty much gone. All the other lights work well. I could do without he low oil light but I'm kind of anal if everything is not right!!!

I think the ground is the one on the upper left. You can see the traces if you look close.

Those sockets fit pretty tight as it is - wire would be too thick.

I solder in new tabs to keep them working like new. You also need to check resistance of the pin to trace connections. The board can look good, but have high resistance there.

Years back, I had one that had a broken tab. I fashioned some alfoil to size and tucked it under the remains of the copper, then folded it into position for the bulb to work. No welding...It worked fine. Might be worth a try to see if it'll still work.

I don't think Huggett has them, despite the website saying otherwise. I think that question has been answered previously in here somewhere already.

The Max fiche lists them as nla. Highlight this with your mouse for easier reading.

I read somewhere that Seibenrock have just started producing the circuit boards and the instrument housings, they have just been shown at the big bike show in Germany.

Sounds good as long as they are producing them for a variety of models.
And it will take a bit of time before that reach the Seibenrock dealers.

Just to remember that the circuit board wiring varies from model to model. And I have also found that aluminium foil helps where the bulbs push in.

It would be more cost effective to have the board repaired by someone competent who has experience in such repairs. That said, I repaired my instrument mylar sheet using copper foil with an electrically conductive adhesive and soldered the tape to the pins. I tried a number of products, mostly silver based, to 'paint' a conductive surface onto the mylar without success. Originally, I believe the parts were made using an electroless copper plating technique on mylar.

Highlighting the pasted bit from the parts fiche in my post 3-4 above shows at least 3 different part numbers...

The post on the upper left of the photo is +12V and is supply to brake, neutral, alternator and oil pressure bulbs. Be careful with the soldering temps as it is easy to melt the plastic in this area.
