12v battery attached to on off switch attached to small set of neon flexy lights 2 pin fuse attached to positive line and i have used a 15,20,25 and 30amp fuse and all have blown. strangely enough its only when the lights are turned off that the fuse blows,if you wire the lights direct whithout the fuse section the wire seems to be warm. can you help me.

SOURCE: 30 amp main fuse blows when the key is turned on.

Can be "nasty problem, for it can mean DEATH, if as you attempt traffic manouvre & it blows !-(As safety precaution , & this TIP would be useful to most all Bikers>Call to friendly POLARIS ATV Dealer & ask for Automatic Re Settable 20 AMP PROTECTOR ( tHIS FITS THE 500 sPORTSMAN A T V & as far back as the 350L 2 Cycle Firebreathing A T V ()Standard Equipment )-Wire that in from POSITIVE Supply on to your loom, & attch its earth ( Negative cable to NEGATIVE > - on Your Battery!--That done, procede to your RecRegulator Unit &Examine Likely "Melting of Delrin (Nyloc, White looking plastic connector plug to terminals of Rectifier/Regulator , Test Output from Alternator., Ensure ALL Eaths have been attended properly, by Unscrewing, & Shining through the Paintwork Refit, tighten & Apply Silicone Sealant ( So that when You "Power Clean" the Motorcycle You wont be "Degrading the EARTHS again!--Now Ride!--If the Loom Loom, near steering head happens to "Short out" The POLARIS Re Settable Fuse Link & Sealed in waterproof covering, will Re Set & then You get chance to further investigate at Your workshop!!Arm yourself with Voltohmyst , or Multimeter OOR mini pointer that can sense Current Flowing, check out ALL Swithes ( Disconnect rear brake light switch & front one by way of unplugging supply leads ( Just possible that You have intermittant short in one of them!--Did You happen to note IF You were turning slightly to Left or Right when Fuse Blew?--Well, look then for "Stress areas for wiring looms, as at Steering Head Stem region, Open the Sheath with Razor Blade & attempt to pull wires apart slightly , then EXAMINE RFOR>bare leads !---With Multimeter You could slowly "ISOLATE" components & IF You had reference to WIRING CHART You then could Painstakingly TRACE EACK LEAD & ENSURE it has no "LEAKAGE "--Best Of Luck & "StayUpright" -Des.

SOURCE: 30AMP FUSE KEEPS BLOWING WHEN I CONNECT THE BATTERY

i have had that happen when i accidentally hooked cables backwards to battery.red cable(pos) to post w/ + next to it & black cable(neg) to post w/ _ next to it is correct.

SOURCE: 2001 ducati 750ss wont start

does it start and run when you jump start it? if so, you probable need a higher cranking battery. sounds like the battery isnt powerfull enough.

SOURCE: blowing fuses,battery too hot

Sounds like the voltage regulator is not working properly.

SOURCE: No power when the key switch is in the run position

Isolate the igition switcw again and set your meter to ohms turn key to acc. test red and red/grey wires 0-10 ohms then turn key switch to on test red-red/grey then red-red/back, then red/grey-red/black again 0-10 ohms the higher the resistance the lower the voltage. Now if that tests ok then it is plug and play i would go to the ground side and check the resistance there is a common ground on the left side of the bike check that for loose or broken connection good luck
