You’re videos have been so helpful restoring my R100RT ‘82!

Without doubt the most comprehensive video on the subject on KZread. Many thanks. I have an '83 R80 TIC identical to this.

HI Keith, I'm pleased this is helpful. Don't forget to click the link in the video introduction text that will take you to the detailed procedure on my web site. The assembly web page and video will be available soon.

Thank you. I expect to be removing the alternator next spring and now have much more confidence.

Hi Cam, Good, that's what I want to happen with these videos is they help remove mystery and replace uncertainty with assurance. As noted in the summary of the video, all the detail about this work can be found on my web site: brook.reams.me/bmw-motorcycle-rebuilds/1983-bmw-r100rs-rebuild-project-index/12-bmw-1983-r100rs-remove-diode-board-alternator-electronic-ignition-sensor/

Thanks! very thorough!

Thank you for the kind words Hurt Locker.

Thanks! I found this useful & presented in just the right amount of detail to clearly follow along. (-: Do you know if my '81 R100-RS would have the rubber diode board mounts? It sounds like something to be aware of and maybe change out as a precaution?

EvLoutonian, BMW started introducing the rubber diode board mounts in 1979. It's likely your 1981 has them. It's easy to tell. Remove the battery ground cable. Remove the front engine cover. Inspect behind the diode board and you can see the rubber part of the mount.

I only have 2 short grounding cables that i can attach to the screw in the block. I have the RVS bolts not the rubber ones. Wil the 2 cables suffice instead of the 4 cable ‘octopus’ you showed us?

1983 R/100, the Gen. light stays on so the bike will only go as far as the battery can take it since it isn't charging. Could you give suggestions on what issues to trace please?

Brandon, check the following: 1: worn down rotor brushes 2. rotor slip rings very dirty or cracked 3. broken rotor wire 4. shorted stator wire 5. diode board shorted out 6. loose charging system wires, or damaged

Great video. My 1980 R100 RS was not charging. I found the diode board had one or two tracks burnt out. What would cause this? I'd like to find out before I put a new diode board in. Thanks Brook

That sounds like the board was shorted. If you remove the front engine cover, but don't disconnect the battery ground, the cover can touch to metal frame of the diode board and short it out.

@@BrooksAirheadGarage Thanks Brook. The bike was not charging so I looked at a few things before the diode board. Battery was definitely disconnected before removing cover. There were broken and burnt tracks on the board. Just wondered what else could cause this

Nice info! Thanks, Bob Belgium Europe

Hi Bob, Thank you.

Brilliant video. Great detail. How similar is this set up to my 76 R100/7?

Hi Dave, They are the same, but your "ignition sensor" uses mechanical points, not the "bean can" used on the 1983 with hall effect sensors inside it.

I really appreciate for your effort for telling how is how!I learn so much for my airhead from your experiences sir.I really wonder where the pulse comes to the rev counter?From the coil or the electronic control unit?

@BrooksAirheadGarage

Aclan, On the stock ignition system, the timing pulse comes from the electronic ignition sensor (also called the "bean can" since it looks like a can) inside the front engine cover. The bean can uses two Hall effect sensors, one for each cylinder, that sends a signal to the ignition control unit under the gas tank. The ignition control unit cuts off the current flow to the coils creating the large voltage across the spark plugs making them arc.

Thank you so much for your kind reply sir.But I want to find the pulse comes to the rev counter on the dash board.I guess it comes from the coil at 1995 R 80 GS.Am I right ?@@BrooksAirheadGarage

@@Aclan Yes, the tachometer has a black wire that runs to the coils. So it sees the on/off of the coil current and computes the RPM from that. The black wire goes to the same coil terminal the black wire from the ignition control unit attaches to.
