I now find myself with a perfectly working Enfield AVL, which is slowly becoming my daily driver.
My commute is 30 miles each direction, mostly highway. Since it's becoming winter, I find I want auxiliary lights for visibility on the road (so others can see me).
I already have a blaring emgo shorty exhaust and a hi-lighter yellow helmet... But I live in Maryland and our cagers are terrifying.
I found this older post which outlines some theory and synopsis of the AVL alternator output:
https://forum.classicmotorworks.com/index.php/topic,25281.msg296603.html#msg296603The last post in that thread summarizes that the wiring harness should be capable of about 20A. I have a 15A main fuse, and a 15A TCI fuse (both blade-style). Please correct my electrical theory below... I am but a layperson:
Since my wiring harness is 15A at 12V, that means it tops out at 180 watts of draw before things start to blow. I have a 12v 7ah AGM aftermarket battery and I strictly kick-start.
It is stated in that above post that the AVL alternator appears to be capable of 220 watts. In this other thread, the alternator is said to output 196 watts per an AVL Electra service manual (unsure which one):
https://forum.classicmotorworks.com/index.php/topic,5855.msg66922.html#msg66922I want to tally up all my electrical draw to see if I have ample room to add some auxiliary lights (without nearing the max of my 180w harness). What all should go into this tally?
- Headlight bulb - 60w
- Brake Light - 27w (1157 bulb) - Running light is only 8.3w -
(Do I need to add both, or does the running light turn off when the brake light is on?)- Turn signals - 10w each bulb, 20w at a time when active
So far, that all totals 115.3w or 107w if we can discount the tail running light.
How much wattage is needed to keep a charge on the battery, and how much wattage does the bike take to maintain its running activity - (is that just TCI and Coil, or is there more?).
Help me classic motorworks forum, you're my only hope!
