Bob:

I purchased from B & C their E-Bus diode with 15 watt heatsink and installed

between Main Bus & E-Bus per your Z diagram.  What I'm confused about is

that their wiring diagram has 1 wire originating from a fast-tab on the

diode to the E-Bus - NO PROBLEM SO FAR: then 2 wires from 2 seperate

fast-tabs joining together then proceeding to a Circuit Breaker then to the

Main Bus....Sooooo I'm a little confused about the Circuit Breaker and why

there are 2 attach points on the diode in the first place.!!!  None of your

Z diagrams show a CB between the Main & E Bus, and why 2 attach points on

the diode joining forces?



Second questions:: Im installing a Heavy E-Bus architecture, per Z-32.

Currently my E-Bus load is around 12 amps...architecture is: 18g F-link at

E-Bus---14 awg---S704-1 relay---14 awg---10amp fuse at Battery Bus.

According to B & C, fuseable links are for low power, 10 amps or less.....so

should I eliminate the fuseable link and directly wire to #10 stud on E-Bus

OR wire to a 10 or 15 amp fuse on the E-bus - and increase the Battery Bus

from 10 amp to 15 amp?



Thanks



Henry

Henry,

	I too am installing the e-bus diode. B & C directions show a

jumper between two of the fast tabs on the diode while Bob indicates one

can just cut off two of the tabs and use the +/- connectors (See page

1-9). This comparison gleans one bit of information from the diode and

that is the fast tab bi-polar to the others is positive. This definitely

connects to the e-bus. Ok, that's easy - Bob shows the tab opposite to

the + (presumed the neg side of the internal diode) is negative and

presumably connects to the master bus. B & C jumps the two opposing

terminals and wires them directly to the master bus.



Someone should decide how these things really wire up. Perhaps they work

either way?



Glenn
