Power Draw through coils

[Guest]

Thanks for doing the math Dan.

Yep should just about be... If you think about the total load of what's on that circuit.... Maybe 85w (20w x 4 bulbs incl the brake light plus 5w for the gear change) if lamps if all are on (if you don't have 4 way flashers as that could add another 40w).

(I don't know what your KOSO draws for gear change & dash flasher indicator but I suspect it's very small so I didn't include anything for the dash light).

P=IV so your 3amp x 14v = 42w.

Say 127w / 14 = 9.1 amps. Of course that figure could rise if the voltages are off (i.e. lower voltage = more amps). It would only be intermittent but you always brake with a turn signal going at some point!

You could consider making more room on the circuit with low power LED bulbs, you should be able to free up 40w easily that way I would think.

Failing that... an inline fuse or accessory fuse block would work fine. Use the signal circuit to switch a relay.

For the record, I was not surprised at his results. I was more surprised that the reality shown on the meters

My reply might have sounded "arsey" when typed - it wasn't meant to be

PJ - no probs on Sums. Jim's reply above is actually for you.

For someone who is electrically challenged (like me) this conversation is incredibly interesting -

Glad i am not the only one.
