We are in the process of testing a new email notification system. Our forum email service has been down for some time. This system allows you to send messages to other forum members, sends an email when a post you're following changes, and other notices that are sent via email. Hopefully this new system will continue to work properly. So if you're interested in a particular post, you can now follow it and be notified when it changes or a new message is posted. That's rather nice, instead of having to check every few days to see if something new has been added. There is also another upgrade to the forum version. Only minor changes, but it's always best to get these changes made. We'll get to that as soon as possible. You can hide this announcement now that you've read it by clicking on the little "X" in the upper right corner of the announcement window. Thanks for being a member. We appreciate your participation.

CDI/Relay Replacements here - Await wiring mods info

Post by ksatter26 »

The proper CDI finally showed up complete with a wiring harness. However, in preparation for reinstalling the CDI we again checked the COBO 12vdc/200A relay (that was working when removed) and found that we must have damaged the relay as we got no "click" on energizing. I ordered a replacement from Polini Parts and when it arrived (with the proper Polini and COBO part numbers) it had a couple of wire connectors already attached along with an instruction sheet stating that we needed to add a wire from pin 30 to battery positive.

The original (as delivered on the engine) did not have this. I sent out some emails to try and ascertain if/why this is now required. Chris, Peer, and Todd were unable to help. I contacted Leon at Polini Parts and he requested my 303 Serial Number to get a response from Polini Italy. We are awaiting that info before proceeding with the installation.

In the meantime, I have started to mask out the cowling "bumps" for painting black. I will run a thin strip of clear sealant along the edges for a crisp outline. Having been warned about the possibility of incompatible solvents, I just came in from running a test on the clear cowl paint/clear sealant/gloss black for compatibility. So far all seems well but will check again i the morning before spraying the black

It's good to be back building again.
