newby aussie with electrical issues

GDay team im new to the site and have a question.Ive got a 2000f4 with 17000ks on the clock.I went to start it the other day and got some wierd electrical signals coming to the dash.there was a relay clicking and the dash lights were dim like a flat battery.turned head lights on and all power gone turned lights off what power there was came back and tried starter and lost power.like i said seemed like a flat battery .put the charger on and the battery is fully charged.What do ya rekon.Ive checked the fuses and as many connections as i could find but no luck.Really to all purposes seems like there is a bad connection somewhere.
PS this site has been more than helpful in the past as the knowledge base here is exceptional.

Ok Jez,

With your nicely charged battery.

When you turn the ignition to on does the fuel pump energise ?

Hi Jez, did you remove the battery to charge it ? Did you reinstall it at all, many a person gets it wrong and turns it the wrong/right way up.

Thanks for the quick responce guys,Yes battery is fully charged and yes ive done the reverse battery install a while ago and got the fix from this forum so no issue there.Couldnt sleep for thinking about the bike not working so was up early mucking around,took the lead off 1 side of the starter relay and shorted it and it winds over strong so plenty of battery power there .Not sure if its the problem but the relay that has the diode on it when I jiggle it around I get intermittent lights flashing going from dim to off in the dash .Checked all the connections and are clean so hopefully its a faulty relay.What do ya think.

cheers Jez

It really seems like a battery problem.How old is the battery?

Okay Jez, after you had the battery reversed and you sorted that out, have you ridden the bike at all ?
On the (some) 750's there's a plug on the right hand side of the bike (near battery) with two diodes inside, checked them ?
Sounds a bit like a bad connection somewhere, swap the two power relays under the seat unit, see if that does anything.

I don't think it's either of the diodes. If you get plenty of power by passing the relay and jumping directly to the starter, and if you get intermittent voltage with everything connected properly, I think it may be your relay. That or a bad connection somewhere.

Jez,

With the bike cranking as you say, did she actually fire up and run ?

I'm guessing not.
