Electrical issue

[BigD07]

I am having an issue with the speedo/tach/bike shutting down randomly. When riding the tach runs fine sometimes or it will be all over the place, the same thing with the speedo. When there are issues they both go haywire at the same time. When this occurs sometimes the bike will die and either turn right back on or I hit the start button and it fires back up. I have a wiresplus kit, thunderheart ignition and dakota speedo installed. This issue seems to have started with the tach and seems to have gotten progressively worse. I have looked for loose connections and bare wires but cant seem to find any. The issue seems to give most problems when accelerating. The headlight will flicker also when revving. I just replaced the HID with a new bulb assembly, the last one melted a couple wires but the new one fixed the issues i was having with the headlight. I have also pulled the tach/speedo apart and didn't find any loose connections or corrosion. I didn't know if the crank trigger or voltage regulator would cause any of these issues. The battery is a new fully charged braille. When i hook it up to the computer through the thunder heart it says its putting out 13.7V. Also have nothing on the key ring.
Thx for any help!

Where did you get the wp?

From Jake at Low Down Chop Shop.

If you bought it from Jake I would ring him directly. He is supposed to have A-1 customer service when it come to things like this. He knows them inside and out. Literally. I'm not sure if you've been on here much in the last few months but he hasn't. I'm sure he'll clue you in.

Did you check the wires under the tank for possible frays or grounding to the frame?

Pulled the tank off again checking for loose connections or bare wires and didn't find anything. Checked the wires from the wires+ install all looked good. I put about 400 miles on the bike after the install with no issues. Called Jake and waiting for him to call to see if he has any suggestions.

Found the issue....I have the Vulcan Works dual coil set up and the two bolts had backed out that tie it to the frame mount. So the coils were loosing ground when RPMs were higher causing more vibration.

Great news, now get out there and ride that baby...:2thumbs:

How did you find it?

I talked to the tech guys at Dakota Digital and they thought I was picking up some bleed off from the coils interfering with the speedo and tach. So I was reading up on the dayna coils and it mentioned grounding the coils which mine does through the bracket. Also for anyone having issues with the Dakota speedo going crazy they said it will do that from to much vibration, which also lead me to the motor mount.
