I have converted a street rod to halogen headlights and ran the wiring straight from the switch through the dimmer to the headlights with no relays -- lights flicker and go out after 5 minutes. I understand this is from a thermal circuit breaker in the Kwik wiring kit.
So, guess I need high beam and low beam relays, fuses or fusible link, primary power feed to relays, and a terminal block. My battery is located in the trunk. How do I size these components?
1. relays - I have Bosch 30/40 amp relays available with 18 and 14 gauge leads, I think -- these seem to be the relays of choice.
2. fuses - what amps do halogen bulbs draw (the Kwik fuse panel uses 20 amps for the headlight switch)?
3. are fusible links better than in-line fuses?
4. is 8 gauge (30 amp capacity) sufficient for a single lead to a terminal block to feed both circuits?
5. what size wire do I need to run from the relay to the high and low beam leads (the Kwik kit uses 14 gauge implying 15 amp capacity for each circuit)?
6. should I fuse the single lead to the terminal block, or fuse the two individual leads from the terminal block to the relays?
7. should I forget the terminal block and just run two smaller wires from the battery connection at the starter to the relays.
Anybody willing to just lay out the design I should be using -- wires, fuses, etc. from point to point?
Thanks,
John
