Main fuse blown

[dublinntv]

As per other post I fitted heat pads to the bike last week and everything was going fine, was out on bike last week and grips working fine as they where yesterday when I left home for college until an hour later when main fuse on bike blew killing all power including engine, this was while I was doing around 60 in the outside lane of a dual carriageway. Scary

Managed to Coast bike into side of road and onto the path, luckily I had enough tools to start stripping bike tried usual stuff headlight connections , main fuse board till I eventually found main fuse was gone. Not fun doing this in rain at the side of the road. Replaced fuse and went to start bike and it blew again, decided to disconnect heat pads and try again this time it worked and started back up.

Not sure what went wrong with pads ( cheap rubbish off the internet) but the only person I can really blame is me, because being lazy when I fitted pads I didn't bother putting a separate fuse in for them, so when they went faulty only thing the bike could do was blown main fuse.

Lesson learnt always fit separate fuse when installing extras to the bike.

How has the fuse blown, Has it splattered apart (short circuit) which would indicate fault, or has it just separated in the centre, which would indicate more of a constant overload( fatique blow)

There may be nothing wrong with the pads, but as you say just should have been fused / connected separately

:)glad you found fault.. had tools and fuses.. sound like
as you say there is a fault on heated pads.. may be able to check
if you have continuity on pads.. may find only one is faulty.
yes in line fuse for pads is the way to go. :)know you get a lot of rain in Ireland,, cheers mate.

I'm gonna try and check pads at the weekend weather permitting.

Reckon it's a short circuit on the pads, when I replaced the fuse and turned ignition on it blew the fuse straight away that was with no lights so no power really being used only the heat pads were still connected. When I replaced fuse again disconnected heat pads bike ran ok. So prob a short circuit on pad or in the wiring somewhere hopefully I will find out at weekend and I will post the results.

Sorry to hear your electrical problems - they are the worst sort! I followed GvS's advice (www.stoeretassen.nl/My_NTV650/Handgreep_verwarming/Grip_heater.htm) and fitted my heated grips on a relay off the lighting circuit. It has the advantage of easily being able to kill the lights and heating (I run a heated waistcoat as well) for more starting voltage, which I've found helpful on cold mornings.

I fitted these grips: www.ebay.co.uk/itm/ROXTER-Heated-Grips-Motorcycle-With-4-Heat-Position-CHEAPEST-ON-EBAY-/171195598429?pt=UK_Motorcycle_Parts&hash=item27dc0d865d and they've done 2 years now and all that's failed is the switch (which they've now redesigned). I just run them off a simple toggle switch at the moment, until I can get round to soldering the original one back together!
