Electrical question

MarkCR750:
Not a Honda but there are some on this forum with good electrical knowledge!, for me electrics = magic!, I’ve fitted small rear indicators on the rear of my Ducati Monster , leaving the standard indicators on the front,  now the indicators flash too fast, the small indicators have 5w bulbs and the standard fronts are 21w, if I fit small indicators on the front with 5w bulbs will that fix the problem, or will the flasher unit just not work properly with a total wattage of 10w per side when it’s previously had 42w?,

SteveD CB500K0:
Assuming the Ducati works like the Hondas, it has a bi-metal strip that heats up and bends when current flows through it.
The bending makes or breaks the contact.
When the contact is broken, the current stops and the heat dies down - and it bends back!

Absolute genius from the 1960s :)

The problem is, if you fit low wattage bulbs (or LEDs), the current won't be high enough to heat the strip in the required time and the indcators either won't work at all or will flash at the wrong rate.

Moorey:
I take it you have fit LEDs. These should cure your problem. You need to increase the load to slow the flash rate.

Moorey:
Just noticed they are too small they are for 10w not 21w. unless you double them up as it says.

Moorey:
Sorry about that these would be better.
