I’m not sure what is going on if I turn key on nothing lights up so I disconnect the ground wire only and turn key on as soon as I put the wire back on the battery then the lights come on and the pump come on only the way I explained it to you 05 Bigdog bulldog 117 cubic in motor s&s

The best thing to do on any Big Dog with a wacky Electrical problem is to have the battery load tested to be sure it is healthy and properly charged. If the heart of your electrical system is weak or poorly connected almost any symptom can happen. When your battery has been checked and reads 12.8 vdc clean the terminals and reconnect it. Don't forget to check the ground cable where it connects to the frame. When all is clean and reinstalled do the EFI reset procedure and let us know the results.
pknowles brings up a point I don't have the answer to but I think he is correct. You should double check your title to make sure what bike you have .

No it only has 4000 miles one owner just bought it it’s been seating for 6 yr in has garage
So yeah the 1st thing you need to do is assess your battery. That’s the weakest link. Load test is VERY important to determine if you possibly have a bad cell. That you unhook it & reconnect & the fuel pump primes would indicate that the system is functioning. Will the bike crank over?

Like I said the battery is good when the battery is in the bike and hooked up properly I try and start bike no light or nothing comes on then I take the battery negative off and turn key on the key then touch the cable to the battery then and only then does the bike light up and the pump comes on ??
Can you fire the bike up after doing this procedure you have come up with? I mean once you have power to the ehc does it run?

Yes it runs great but I’m pretty sure this is not right?
Absolutely. Sounds like you have a ground issue. Check all your ground connections. Clean & tighten them. I know you said the battery is good. I assume that means you did get it load tested & it checked out?

Yes I did a load test I did figure out that the wire that goes into the module if I lift it up and touch it back to ground that’s when everything works again if I leave the big ground in the other ground on the battery and just lift the one that goes to the module then it will start ?
