Have you tried running it without the OC connected and check the PC plug where it goes into the ECM, big source of problems.

i disconnected the pc and applied wd 40 to connectors. bike ran fine for about 80 miles but has now started popping again and the same code po662 is back again.

Thanks Glider, just what I needed.

Glider (oh great wise one!)

I'm fitting a 1999 HD radio cassette to my 2005 FLHT Standard. Research showed many R-C people upgrading to CD (both NOT Harmon Advanced units) OK so I figure backwards works too.

All plugged in OK. I have not fitted the speakers yet but when I power up I get "BUS ER" on odometer.

Could it just be that the speakers are missing, hence Serial bus open? All the radio remote controls work fine.

Many thanks in advance

Powering up with no speakers is a good way to damage the radio. As far as the bus error, don't know why that happens but it's no doubt telling you something is wrong with the hookup.

Glider,

Well - all installed, radio works fine, remote controls work fine but "BUS ER" is still there. Unplug main radio connector it goes away.

All I can think is I damaged the radio by powering up with no load (speakers) or radio is incompatible with later model year (99 radio in 05 FLHT).

All advice gratefully received!

Can't add anything about the "BUS ER" here. Sorry.

Glider,

All fixed!

Older radios don't have speed-related volume; remove and tape-up pin 9 of the main radio connector 27 and all is well.

Go the tip from another H-D forum, sorry! (Googled "Harley 'bus er' radio")

Many thanks for the help.
