I have a 06 Mastif when I turn the key on nothing. I have checked the switch cleaned all conections to ground ,batt,plugs, ect. I left the key on while I checked things out and walked away and power came up. The bike seamed totaly fine but it went out as fast as it came up. No power to anything.WTF

Dumb question, have you checked the battery?
Load test ?

Could have a bad key switch, happened to me a few years back.
My money says switch for sure... I have seen it a few times on them factory switches and them cheap replacement tractor supply switches.. like physically seen it

I went with OEM replacement, got mine off ebay.
That’s how I would go if my bike was set up that way. The factory ones were crap, supposedly the redesigned ones from D&D are better...

The new 5th gen's work just fine and you get 2 keys. The only thing is these where designed for on/off and and accessory but they cut off the 2 leads and shrink wrapped them, so you have to turn it an extra click to turn it on. (I have one) but the key never falls out. BTW - There are more combinations with this setup so less chance somebody else has your key.

Thank you all for the response I was really feeling the switch was the problem so i tested it with an ohm meter and it seemed to test good.
But after 11 years i'm thinking it could be worn out. Ill try to find one. Thanks

I was really feeling the switch was the problem so i tested it with an ohm meter and it seemed to test good.
After how many years copper meets arc with said wall switch in said house? Test good tests goodenuff for me. So if I may interject a few mental notes:
1. Leaf Blower - in hand, turn it off, move the line, pick the blower back up an nothing. Walk to the wall and note plug is still secure from A to B. Split the blower apart, check on/off switch and checks good. Go to the commutator and sand the copper clean with fine grit sandpaper if not scotch-brite. Assemble blower and toggled switch. Return to the backyard and blow away.
2. Motorhome Ground Wire - Have the engine cover off, pour fuel down the carb, turn the key and no start, but an arc made that caught out of the corner of my eye. It was the frame strap to engine. Remove ground strap, file both contact points till I see fresh metal(s). Engine fires right off.

Take my empirical knowledge over to here on this thread, walks me up to the key switch and sanda contact points with a straight edge razor. No wait, OP says switch is good. Unless I make a visual and black arc be the clue. I'd then find said strap from frame to engine, engine to battery post. I'd then find the end of said strap or cable to engine/frame. I'd then hold the starter switch and aim the temp gun at the ring of said strap/cable, if not touch with said anal thermometer, or finger it for the 2nd degree fell of it. Take said meter, set to ohm and find ground [wire] on the key switch, and ground both frame/engine with the other meter probe. Set meter to 20-volts, with key on, ground probe(-) to frame, and probe each wire off the key switch to note voltage. With meter still set at 20v, probe (+) to the hot side of the battery, neg-probe to hot wire of starter relay.

I have a key switch on the way I'll let all know how it works. I'm ok with other people riding when my bike is ready to go. But when i'm broke it really bites .

Well The key switch wasn't the problem. Turn on the switch and wait five min and power comes on all by its self and
bike runs fine. Turn off the bike and it may or may not power back up when the switch is turned back on. WTF
Thanks for the suggestions though .
