This is the brand new adapter and I did wired up as specified.
Thank you again

Looking at that adapter, it seems like it has 4 wires. Is this true?
Describe the instructions for installation.

Also, you can connect the tach signal wire to one of the coil negative terminals to see if the tach actually works...it just will read incorrectly.

Tach works without the adapter, just half the RPM. Green to one black wire coil.
I owe you one. That means I need a different adapter (for a metric bike)? Or I can build my own like I've seen on the site.
Any suggestions from someone is appreciated. Thank you

Miller time. Stay thirsty my friends.

Take a look at this:

Note: diodes must be reversed to what is shown in diagram.

I am not sure what you have there, but it does not seem to work.

This is specific for Harley in description... so now we know they can not be used for metric bikes.
Thank you again

You are very welcome.
Post back if you have any more problems.

I'm not so certain. The Baron adaptor works on both HD and Metrics. With the Baron no tacho wires go to the coil. The green tacho wire goes to the green adaptor wire. From the adaptor the yellow & blue wires go to negative side of coils (one each).

I had a look on ebay and that adaptor comes with 3 leads. If you have a 4th lead then that is an optional resitor to help with needle bounce (according to the description).

With any adapters no tach wires go to the coil. The problem with these adapters is that they are bulky and hard to hide. That is the reason I got this slim one( just 3 wires and no box) on ebay that did not worked out for me. But I will build my own next week and sell this one on ebay for the Harleys.

Post back on how you get on. Good luck.
