    • Do not hijack another member's ad by posting unsolicited commentary. Example: if a member has posted an ad offering an anchor for sale, don't add a post to his thread stating that you have an anchor you'd like to get rid of also. Posts deemed as unsolicited commentary may be removed.
    • For your own security, do NOT include your e-mail or phone number in your ad. Instead request that interested parties contact you via PM (private message) to provide owners contact info.
    • Brokers, Dealers, or those with a commercial interest in a sale are prohibited from posting in Classifieds.
    • Only Trawler Forum Commercial Members may post ads in the Commercial section. You must be a designated Commercial Member to start threads in this section of the forum. (Contact a moderator if you have questions about this)
    • Don't post links to commercial sites where you are also offering the boat, such as eBay, Craigslist or Yachtworld, etc. unless it contains a more in-depth description, additional information or pictures.

  • Avoid Scams.

    Our classifieds are free and anyone registered here is welcome to post an ad.
    Be aware that there are unscrupulous folks out there. Avoid any interaction that seems odd to you or �feels� wrong. Inquiries from unknown buyers, buyers �agents� and other non-traditional approaches should be treated with extreme caution.

    Beware of unsolicited contacts offering to put you in touch with someone else who is buying or selling via e-mail or text.

    Do not post your e-mail address or phone number in a classifieds ad.

    Hints that you may be dealing with a Scammer:
    • Seller or Buyer approaches you via a direct email or PM and then steers you to an off-site communication method (text or email).
    • No posts or very few forum posts.
    • Recent forum membership
    • Insists on conducting negotiations via email or text rather than PM
    • Requires payment via Bank Transfer, BitCoin/CryptoCurrency, WesternUnion or other unsecured method.
    • Buyer or Seller suggests Paypal "Friends and Family" payment. Paypal is a good way to arrange payment but an invoice for goods and services should be used rather than "Friends and Family". "Friends and Family" avoids fees BUT there is no recourse if the transaction runs aground. Friends and Family is for gifts only. There is no protection for Friends and Family transactions, so never ever use it to buy something.
    • Declines to allow viewing the item before proceeding with the transaction.

Looking for a 1980s VDO -80/+80 A ammeter to replace a failed one on a GB instrument panel. Who can help ?
 
Guessing from the question you want to match the face exactly? If so can you post a picture?
Otherwise almost anything will work.
 
Google “VDO Instrument Repair”. VDO gauges were also used in cars and trucks and there are more than several companies that support our old gauges.
 
Old VDO ammeter

Thanks for your attention
Here is a photo of a similar ammeter from the fly deck instruments panel. The faulty one is on the saloon instruments panel but covered by a wooden plate level to the top of the transparent part of the instrument. This is why current VDO ammeters are unsuited.
Best regards
JeanL

I used lauderdale speedometer to repair a faulty VDO tachometer, you might contact them for help repairing your gauge - lspeedo.com
 
So the panel face was cut large enough to fit over the finish ring. If you remove the gauge, the outer black finish ring should be removable and the actual gauge unit should be interchangeable.
I will still check for a matching one. Will take a couple days.
 
Thanks Turtle Blue
You’re right ! The black outer ring is removeable but the replacement instrument itself must have edge tenons to hold the ring. Therefore I keep relying on this old model
Anyway, I’ll try to have my ammeter repaired by an automobile electrician.
Best wishes

Personally I would not replace it with another one like the original but rather get a current technology amp gauge. It may not match but it will give you way more information than an old school ammeter.
 
Analog style amp gauges have pretty much gone away. I checked what I have from the last couple of change outs and they were all volt meters and white faced.

My choice would be to swap out the one from the upper station if you want to keep everything matching in the finished panel and then find something you like for a replacement, possibly a multi function unit. You can glue the exterior housing in place to minimize the visual difference. Or just keep checking E-Bay.
 
Thanks once more Turtle Blues
That’s what I did. I got the working ammeter at the lower station and watching Ebay, found an exact match for the depleted upper station. Bad luck, this new one appears to be dead too and I don’t know how to check those f… machines
All the best

As suggested above you may be able to find a repair facility that you can send them to if you want to stay with that gauge.
My 2c thought is you may be able to find an aftermarket gauge that fits the space and uses a hall effect sensor that slips over the wire to generate the gauge signal.
 
Count me in on the new tech too. Would I want an old style ammeter with a built in shunt? No.

A remote direct wire shunt would be better and a new wrap coil powered one even better still.

When considering fixing vs upgrading you have to consider the cost. In this case the cost is low. You can get better (new tech) for less dough than replacing old tech.
