Certainly quick to install, but the price.... A new build 2AV54 (a Chinese manufacturer has now acquired the licence)  is around $US20, a JPT 3-way plug is around $US8 and 20m rolls of high temperature insulated wire (enough for a lifetime of Beancan rebuilds) are $US8 each. If you are adventurous a Siemens HKZ101 can be used as a direct replacement for the 2AV54, I would have thought that the HKZ101 was not as "robust' as the 2AV54 but people have been using them in both Airheads and Bricks for near 20 years and nobody is complaining about premature failures.

Actually this device doe not solely test the ATU as it relies upon the ICU to supply power to the ATU and to "switch" on signal from the ATU.

This is not a bad thing to have, but it will not assist in isolating a ICU/ATU fault, it will only tell you if the whole system is working.

The ATU can be tested with a 9v battery, a nice bright LED, a 1k ohm resistor and alligator clip test leads (electronics places sell them very cheaply in bundles of 6, 12, 24 etc - they are very useful) - Connect the +ve and -ve terminals to the appropriate pins on the ATU plug and then the signal (middle) pin to the +ve side of th eLED via the resistor, ground the other leg of the LED to the -ve terminal of the battery - total cost under $AU10, and under $AU5 if you already have a 9 volt batttery or a "shop" clean power supply.

Testing ICUs is easy - with no gizmos - the ICU should trigger a spark every time you switch power to it (kill switch), no spark on switch-on, time for a new ICU.

I second Tony's advice about the ignition tester. One can be made for the cost of the 9V battery (represent 90~95 % of the total price).
As per the Hall effect sensor, I prefer the Siemens HKZ101 because it is way easier to rivet. As far as I know, the specs are identical for both the Siemens and Honeywell so performance wise they should perform the very same.
I've repaired about 10 bean  can for friends. The most difficult part is riveting the  new sensor in place. In the case of the Honeywell, it is a PITA. Then comes the soldering of the sensor wires on the existing harness and insulating them with shredding tubing sufficiently short and thin not to be caught by the aluminum vane and cut.
It is not rocket science. just need a little precision and good job. So the price tag on these items seems too high for me.
But it's just me ;-)

I checked the honeywell on alibaba and they quoted $30us.

I got mine via Ebay and Germany when I needed them. They were around 14~16 € each at that time.
Price should be quite identical between the two as they are the same specs.

I checked the honeywell on alibaba and they quoted $30us.

Glad I bought mine when they were $US20 then.

Still, even at $US30 they are a couple of hundred cheaper than a new or even a reconditioned beancan.

are less than the one you found.
In Germany you find the CYHME301 compatible for less : http://www.hallsensors.de/CY-HME-GTS-PriceList.pdf

Should you wish to eliminate the Bean-O can, check out the Hall sensor triggered options offered by John Rayski at EuroMotorElectric.

These are Chinese knock offs. Not manufactured by Honeywell.

These are Chinese knock offs. Not manufactured by Honeywell.

At least one of the Chinese suppliers did at least go to the trouble of obtaining a licence from Honeywell.

I will be putting a bean-can with one of their products in it into service shortly. I will report back on how it goes.

Hello !
I've found the Robert Frankham tester I had saved somewhere on my disk.
See the attached picture. The two pole switch at the battery is not needed as there is no way the battery can discharge when the device is unplugged from the bean can.
I've bought the 3 prong AMP Junior Timer connector in Germany here : http://www.kabelschuhe-shop.de/product_info.php?language=en&products_id=7983 but I bet you may find some near your home...
This device is quite identical to the factory tool used to set the static timing point. Motobins used to sell the factory tool for a... huge price ....
I've made one and it is useful to find if the ICU or the Hall effect is at fault.
Tony, I've found that in some case, operating the kill switch produce a spark with the ICU dead. So this troubleshooting method is not 100 % fool proof.

I'm surprised about anyone willing to support a range of motorcycles from '81 to '95 with a bit higher technology .

The newest of these bikes is approaching 22 years since they stopped production .

I wonder how many BWM bikes from the '81 to '95 model years are still roadworthy???

I never meant to say these parts were cost effective to an owner that works on their own bike, just surprised that they are available .

[georgesgiralt]

Bob,
some years ago, I asked a French BMW representative on that very same fact. He told me that around 50% of the total BMW bikes produced where still in good shape and running (well able to). So it was a lucrative business for BMW to deliver parts for them he told me.
