Wiring Schematic Fuses

[chadjmccolm]

Context

Fuses were not used in the prototype of the wiring harness because many of the operating currents were unknown and time was a large constraint. The wiring harness should have some form of built it fuses - whether inline or in the design of the switchboard (assume that is made). At the least, fuse sizes should be determined and added to the existing wiring.

Outcomes

The outcomes of this project are as follows:

• [ ] determine which components need to be fused and how large those fuses must be
• [ ] protect the controllers in the wiring from excessive current expose caused by shorts elsewhere in the harness

Constraints

• fuses must not impair function of the wiring harness

This issue has been folded into #23

Here are the draws found experimentally:

• Injector 5A peak
• Microsquirt 0.5A continuous
• ETB Driver maximum 12A or will overheat
• Fuel Pump 6A nominal
• Fan 10A in practice. May take up to 15A.
