    Don't forget I used to be an auto electrician, so I will definitely observe those things 🙂

    Case closed. I was curious if anyone was using automotive cable. Turns out some people are. So will I 🙂

    Without looking it up, I wouldn't be surprised if it's to do with fatigue. Aluminium wire I reckon would crack easier than copper. I feel it would have less flex I had no idea it was being used for starter motor cables though 😲

    That's getting a bit academic. I'm not building a 11kv transmission tower! Everyone uses copper cables for starter motors. so will I. Lucas sometimes used aluminium for field windings in their starters. The copper tag of the brushes were spot welded on. If you had to replace them, normally you would cut off the brush, leaving a bit of the copper tag behind. Then bind the new brush on with a single stand of copper wire and solder. One place I worked at did a lot of vintage stuff, and someone had a roll of 'aluminium' solder. Not sure what it was made from. Apparently unobtainium, because you couldn't buy it anymore. But it could solder copper to aluminium! I never used it though.

    When you say some manufacturers, do you mean aircraft manufacturers? It's certainly best to keep the lead as short as possible. You need cable going to a starter motor. It needs to be flexible.
  7. danny_galaga
    Fully agree. We always soldered our cables with gas. The flux was a paste from memory.

    Particularly the 'motorbike sized' starters like Rotax and Jabiru. Just curious. Would be much easier to set up with automotive than tefzel. You can get pre-made lengths easily enough. Obviously a drawback is it would be more likely to create smoke in a dead short situation. My thought is that with an isolator, it shouldn't be a problem. The run is quite short in my plane too, which also reduces the risk of a short.

    I think they use reduction gear starters now. Pretty sure my Victory did. At one stage Harley were using Hitachi starters 😄

    Yeah that pic seems to be an aftermarket part from Turkey. Delco were ok. My own personal opinion was that Bosch were the gold standard in quality. Nippon Denso weren't bad (and as we are noticing on this little journey, quite ubiquitous on small engines). At the bottom of the heap in terms of design and or quality were Lucas, prestolite, magnetti Martelli and Hitachi There were niches of course. CAV made really good quality truck starters, albeit complicated. Bosch next in truck starters, then Delco. Delco weren't bad mind you. Just a bit simpler. Easy to overhaul though.

    Damn it was hard to find a 3 brush starter example. I thought I was losing my mind 😄
  12. danny_galaga
    Looks like the latter Rotax starters are 4 brush, and the earlier black starters are 2 brush
  13. danny_galaga
    It's a very small force compared to everything else going on in there. A lot of the 2 brush jobbies are 90 degrees to each other. On my accusation of a RO-tax on the starter. Maybe I was too harsh. Here's the price for the similar Suzuki starter mentioned earlier 😲 https://www.cmsnl.com/suzuki-vx800-1990-l_model14275/partslist/FIG-23.html#.ZDZm6WR_U0E Price for that after market one is about $210 including freight as far as I can tell. 🤔
  14. danny_galaga
    Oh actually, I think maybe two on one side and one on the other because one of the poles (I want to say +) might run hotter...
  15. danny_galaga
    Most car and truck starters have 4 brushes. Some of the smaller Nippon Denso car starters had 3. Maybe I was mixing up that memory with something I'd seen recently! I never knew why 3 when I was an apprentice but I'm thinking it would be a way of increasing resistance for a lower current draw on existing 4 brush designs. Why not two then? Haven't the foggiest 😄
  16. danny_galaga
    Apologies. I could have sworn I saw 3 somewhere!

    You know, I've thought about it since more, and I'm tempted to buy that German after market F650 starter for shits and giggles. If it turns out to be not useful, it will be easy to sell on...
  18. danny_galaga
    That's a two brush starter. What did you do for the third brush? Or were they ok? Can narrow down those kits to a f650 or vx800 starter. If you need to change the brushes for instance, there can be different compounds. That can make a huge difference. For instance, the only difference between a 12v 40mt truck starter and a 24v 40mt truck starter was the brushes, and you didn't undercut the commutator bars.

    "Guten Tag The F1205 is sold out. warm regards" Oh well.
  20. danny_galaga
    Yes that's the first link I found. That seems to be a car dealer. Doesn't matter, I'm sure there'll be something closer to home. The only problem now I guess is if the last model to use that starter was 2012 (not saying it is, but if it was) then NOS of starters is going to be thin on the ground. Motorbike starters wouldn't be a big seller to begin with. I know myself if it was my bike and it was out of warranty, I'd hit the wreckers first before going new. And then we are back to the aftermarket one. I'm sorry I opened that Chattanooga Choo Choo link now, it's screwing with my edit function... Let's see if I hear back from that German outfit.
  21. danny_galaga
    Do you have a link?
  22. danny_galaga
    Yes I still think of them as Nippon Denso. The Denso solenoid is made in Japan. Wherever the Denso starter is made that Rotax uses will be good enough for me 😁 So if it is an F650 starter, wherever Denso gets it made is obviously speccy enough. Although I think most of their motorbike starters are still made in Japan.
  23. danny_galaga
    Good point, except that a badly made starter can get just as explodey as one that has the solenoid stuck on, which we decided in another thread might not be good for your engine. Although now I think about it, no shrapnel from this design of starter can get into the engine if it disintegrates. Maybe aftermarket would be ok to try, so long as you don't mind a dead short for a few seconds while the armature windings hit the magnets 🤔 Onetrack, Australia is not the UK so I doubt brexit would matter to a German supplier sending to us. a lot of the stuff vectriq are selling is made in Holland for instance. However I might try and contact an Australian BMW parts outfit about the F650 starter. See what they would charge.

    They have quite clearly sourced the correct genuine Denso starter 🙂 I have shot them an email to ask about price and availability. Sometimes, like with my fuel pump guys, the info stays online years after the business has gone under. Let's see if they reply.
  25. danny_galaga
    I have dealt with them before. Great service. They stock the aftermarket regulator/rectifier for the 912 that I bought 🙂 https://www.vectriqparts.com.au/product/rotax-voltage-regulator-carr5115/ I am becoming somewhat confident the starter is the same as the F650, so not too worried about the VX800 unless that is more easily had and at a great price since it sounds like you would have to swap housings. Doesn't look like vectriq does either. And while the aftermarket regulators are an improvement on the originals, I'm not so sure of the quality of aftermarket starters. That's a much harder thing to emulate well than electronics. If you are ok with aftermarket, then the guys I linked to earlier would be a source (provided I am right about the F650 being the same starter) https://www.stein-dinse.biz/product_info.php?language=en&products_id=524427#prettyPhoto
