Default Electronics noise

Has anyone found a cure for the ground loop problems on the ST? I had to add a stand-alone 12vdc battery to get rid of the whine and other noises when trying to use both the J&M Integratr IV powered from bike 12vdc and my TOM TOM 910 also powered from bike 12vdc.

Any two devices that share the bikes 12vdc power create a very bad signal to noise ratio on the output of the Integratr IV.

I have tried various ground loop filters with poor results.

Also is it possible to charge a small 7 amp hour lead/acid battery from the bikes charging system with out over charging it?

Any electronics experts out there?

Clapping

Yes you could parallell both batteries to the Bikes Alternator.
There are some good examples on the internet on how to do it.
BUT!!! Think of it this way ...you are connecting that battery
into the Electrical system that you deem suspect in the first
place! The voltage/Amprage flow is do to a chemical reaction
in a wet cell battery and will not pass interference.The problem
lies in the wire connections at the battery terminal point if
you connect them together if you are trying to run everything.
If you just want to charge the battery and remove it for use
read below.

BUT!!!!! First and Formost check with HONDA!!!! About your
issue! Warranty etc.The local Dealer may not have an answer
then go to HONDA!

Second is to check all battery and electrical connections etc.
All ground points is most important.Scotch pad any suspect
connection points, use a Battery Terminal Protectant from any
Auto parts store on the terminals connection points then tighten.
Learned this trick with boats and the Telecommunication field.

Third where were you grounding the Filter/Choke coils to? In
TeleCommunications it is ground back at the Primary Voltage
supply in this case the battery.


Hope this helps and in my opinion again check with Honda.

Don't mess around. Call Mark Reis (our electronics wizard) at 425-335-1296 and tell him what's happening.

He'll probably just tell you what to do over the phone or, you can ride in and get him to fix it for you.

He will be out of town until about Nov. 15th, however.
