Connected battery wrong way round
« on: April 17, 2021, 02:00:48 PM »
Hi Guys

Done a really stupid thing and connected battery wrong way round :191:

I have no power at panel, all fuses are ok except one under battery which I am going to check now.

Have I blown the ECU or instrument panel etc :084: :084:

I well annoyed for being so stupid

Hi Guys

I happy , only blown the 30A fuse, now running ok :152:

At least I learnt how to change the fuse, what a stupid place to put it eh :151:

Got to be worth a few beers  :031: :031: and a ride tomorrow

I would like to think that Triumph built in protection against the battery being connected up the wrong way which is all too easily done. However, not really sure what form that protection might take and why the 30A fuse blew in this case.

I have done some googling and it something to do with a diode that protects the bike and causes the 30a fuse to blow.
I done 120 miles today and running prefect ❤️😀

I think the diode you mention is in the voltage regulator circuit of the reg/rect?  :187:

I believe reverse polarity protection circuits normally consist of more than a diode. However, a very simple means of protection would be to connect the output of the 30A main fuse via a reverse biased high power diode to ground. With the battery connected the right way round, this diode would not do much. However, if the battery was connected the wrong way round, the diode would short to ground and the high current through the main fuse would blow it.

The problem with this approach is probably the time taken for the fuse to blow during which time other more sensitive bits of electronics might be damaged - hence the need for something slightly more sophisticated. I looked at whether the rect/reg would provide this diode protection. In the simple rectifier set up in old bikes, its diodes would work in this way but, with a regulator in series, it is much less clear what would happen.

Judicious in principle, but how do you recharge the battery with the alternator and regulator integrated into the motorcycle ???

If I understand your question properly, the charging circuit is common with the battery terminals i.e. upstream of all the outgoing circuitry.
