Just seen this advert, anybody know anything about this company? A quick search didn't show anything.

Thanks Mark. It would be good to see what you can find out.

Got it!

I will get a new battery at the start of the new year. I am a bit windy about connecting the new battery to the old one but in theory it shouldn't harm the new one but maybe it will trigger a fault in the new one? Is there any merit in connecting a single 18v battery to the old one? Or 2 x 18v in series? I have loads of them! The consensus seems to be that if the battery are completely discharged then you have to reset the BMS with the Stihl software, but I've not actually had this confirmed yet as the Stihl software is very expensive, plus I suppose the quickest and easiest method is to chuck a new battery on the thing. Mark at Skyland said he would look into putting a battery on his diagnostic but for sure it will not be high on his priority list! I think as these battery things get more popular it would benefit from understanding the functions, but the manufactures also have to want to do this. My brother has a 12 month old e-bike which he stupidly pressure washed, water got in and it blew a diode or whatever in the BMS board. No help from the manufacturer - just buy a new battery!! It's fixable if you recognise the diode, but it burned and can't read anything on it. Tried to find a hobby electronics' person but don't know one. In the past I used to send all my faulty car music centre's to a guy who was an electronics' wizard at an RAF base, he fixed everything!! If you need manufacturer's kit to remove codes or switch thing on again then we're snookered!!

I'm going to try to repair the existing housing pin first. I plan to machine the pin with a new circlip groove and lower the nylon engagement part to allow the washer and circlip to be fitted. I know professionals are not keen on the ergo starts for every day use, but they have a place for the firewood cutters who are elderly or physical compromised and require a quality machine. The only problem I have is remembering not to drop start them. I can buy a new housing inc shipping for £74, or buy secondhand none ergo for £63. I haven't checked with seller above if the are Motronic or not as well as they are different. If I could find a secondhand ergo start from a 261 or a 291 that would be the answer. The only other issue is that with the ergo start, saw is not fitted with a decomp valve although I don't think it would be a problem for 90% of users, I can still start my Husky 2100 and Dolmar 9000 without a decomp at 67, what is the general opinion on this?

Totally agree on the time, I'm retired so don't mind spending some time on research and a bit of messing, it's a hobby for me using saws and repairing / maintaining them. If you had to pay for the time it 100% would not be economical, but I hate waste and adding more stuff to the scrap bin so worth it to explore the possibilities of reclaiming something and sharing the experience with others. The majority of my saws have been reclaimed from 'spares or repair' pile and find it keeps me active mentally and physically repairing OPE and cutting wood for my home and maintaining a hectare of woodland plus looking after numerous neighbours equipment as well. I don't like the throwaway society and being a mechanic by trade it's in my blood to at least to have a go at fixing things.

I'll probably get another battery - I only have one, then I can try this, just a bit concerned it could damage a good battery, is that a possibility?

Thanks, you and Kram suggested this route, for £10 worth a try, I'll let you know, set ordered!

Any info on this Mark?

I have the guide which I got a few years ago, but decided I should spend more time on freehand filing and never used the guide! I think like you, for the 1/4 chain it would be better without.

There doesn't look to be much in the way of BMS electronic circuit board in there, but it maybe behind the charge level lights and reset knob, I will strip it again and look for it.

Good idea! I've got a Dremel and I think some 4mm rotary Granberg bits, I'll give it a go! Just got to get the battery up and running.

Correct! It has a torx end but I didn't see a purpose, I haven't stripped it down fully yet as it didn't show a replacement shaft on the parts diagram. What I was looking at doing was to bore the plastic starter piece (number 23) down by 5mm or so and machine a new groove in the shaft for the clip. Next job is to see if the shaft can be removed or is moulded into the cover.! Thanks for the offer on the machining.

Thanks Mark, I was hoping you had some insight into these Stihl battery thingies!

I will have another look over the next few days. It looks quite difficult to get to each end of each battery.
