Hi , Thanks to all for replying to my previous post regarding the above . A correct Lithium Ion battery was purchased , I came to remove my seat only to find that both seat bolts had seized , and upon research found that this is common with Fireblades , weather this is just the 2010 or on all models it seems that Honda use cheap seat Bolts and is quite common . Upon further research I also gathered the only way to get round this was tor drill the heads off the bolts which was done and was finally able to get the seat off and replace the outmoded Lead Cell battery . It was definitely worth doing , and the seat would have had to come off at some point anyway but now the horn doesn't work which is a bit of an issue as its due for MOT at the end of the month. I've checked all fuses and have everything else apart from (Horn) and whilst its nothing to loose sleep over just wondering if anybody else has had a similar experience . ?? Peace
Assuming the horn worked before the battery swap - the new battery wouldn’t make a difference. So either a connector has been disturbed in doing the swap or purely by coincidence the button or horn have failed. Check by a process of illumination. Put a meter on the button and see if it’s getting 12v in - if not then it’s a fault in the loom/connectors between it and the battery. If it’s getting 12v does it send it out when pressed. If not it’s the button - try a spray of terminal cleaner. If it is sending is it getting 12v at the horn. If it is then has the horn got a good earth? If you don’t have a meter take a temp live feed off the battery directly to the horn positive side and it should sound - if not remove the temporary live, do a temporary earth and try the handlebar button does it sound? If not do the temp live to the positive and temporary earth. If it still doesn’t sound, it’s the horn.
The seat bolts can sieze or difficult to remove. The first mistake I made on mine was to use pozi head screwdriver; you need to use philips or JIS heads. You can buy buy a hex pan head bolt+shoulder as an alternative. I have kept my OEM bolt (they are not cheap quality but can develop galvanic corrosion) with rubber washer.
