That said, a) the entire aftermarket parts business is based on figuring out how to do more with less; and b) the present utterly insane laws about the duties of publicly-traded companies to maximize short-term investor profit fly directly in the face of maintaining brand quality. > > Regardless of the source and quality of the ignition switch, IMHO, the >starter and > > headlight currents should not go thru it.

The starter solenoid only draws a couple of amps. If VW can't build a switch to handle a two-amp load, even a two-amp inductive load, they really should close up shop and go home. The headlights draw ten amps on high beam, if you use 65/55 lamps in a two-light setup. The 2.1l add another 8+ which is pushing it a bit. Relays certainly make sense here, both because they offer the potential to reduce voltage drop to the lights and because they offload the heavy switching to a standard cheap part that isn't specific to one particular thing. Depending on the cost of copper it might make sense for them to use a skinnier wire to drive a 200 mA relay that drives the two-amp relay/engagement mechanism to drive the two hundred amp starter. But saying they "should" have done that I think is beyond reasonable. Yrs, d
