Perilously brief hazard run time

[postoak_imp]

I don't really understand all this but shouldn't you hook an amp meter to the battery to confirm the figures you calculated when you turn the hazards on before you do anything else?

Anyway, I'm more interested in the fact you live in Greenland and use your CB1100 as a police motorcycle.

I am not too sharp on electronics, but I can follow most of your calculations..are you calculating the momentary spikes of power usage .. like on the flashers, is it 50/50 .. 50% battery draw, then 50% rest ? maybe you have that figured in there somewhere and I just didn't see it.. do you have any pics of your bike? does it have bags and rear box? how about a reserve battery balanced by installing it in the top box.. it will raise the center of gravity a little , but may be another solution.. when I had my boat, I always had a dedicated battery for starting the engine.. it was always a bear to try and push start it !! .. haha ..

On a turn signal system based upon load, rather than time, a 6 ohm resistor (rated for 50 watts) is necessary to replace the load of two 27 watt (2.1 amp) incandescent elements on each side. If that is done, there is no battery load savings using LED.

I ran LED for brake/Tail (for longevity) but not for turns on the CB1100.

2 of the 4 can be replaced and still flash, but it will be a hyper flash.

Thank you SportsterDoc... sounds like you've dug into the details and know what you're talking about from experience. I can't solve this at the load end by buying a bulb and just sticking it in there. Maybe I'll go to the other end of the circuit and see if there's something easy I can do there... add the brains to the control end Honda should have in the first place. Thanks.. and it sounds like my estimate that my rears were using both filaments was off too but I'll drag my daughter into the blame for that... looked like it to both of us

Thank you again.

Hi Postoak... Thanks for that suggestion... they were too simple to worry about verifying. Famous last words but if I'm off, I'm sure I'm still within a factor of two which wouldn't change the big picture. I did measure the run time of the hazards and it's within a reasonable distance from the computations. I got about 50 things on my MUST BE FIXED list and no time to chase accuracy

I have two police motorcycles (KZP's) I use to work various skills and ended up helping with training. The CB is in my garage because it works.. I just needed something that hadn't been ridden to pieces. But while I'm a semi-passable rider, I would have to say my abilities in geographical matters are drastically less

I didn't factor that in Chuckk... excellent catch. Adding another battery will get me ~20 min run time to a no-start end The designer in me is pissed off this got out the door at Honda... I think too much of them to just say "no problem... I'm sure they tried". They phoned this part in. I can see how this will create danger for some people where it was just too easy to have avoided. I started , and got some ways into, writing a book on bad technical decision-making once and there was a chapter called Excusable vs Inexcusable Stupidity. I'll leave this at that. My blowing the duty cycle modifier... inexcusable if you knew what I used to do Ditto, Honda. Thanks for catching it.
