[s-cars] HID install weirdness

[JC]

Peter -

Totally common symptoms from an HID install.

Re: The tach - they suck a shipload of current on startup which sometimes
seems to drop the system voltage for a second causing the IC to have a
brainfart. What seems to help is a new and preferrably uprated 14.5 or 15v
voltage regulator in your alternator. That seemed to stop it for me and also
solved my LS2 coil incompatibility.

The boobcheck is a different story and less of  a conclusive solution.
Happens to the majority of HID converters it seems - not right away usually
but after some time. From this I am purty shure that the increased current
somehow burns out something in the autocheck.  I "solved" it for a while by
replacing my autocheck but the junkyard replacement lasted about 4 months
and then started going off again. So the new "solution" has been autocheck
disable by my QW documented pin-bending technique which is not ideal as I
kinda like knowing if my bulbs are all working or not without wandering
around the car in the dark periodically.

I bet a box of belgian beer that relaying would truly solve both problems as
it would insulate the bulbcheck and IC from the 'unusual' HID current loads
(aka very high at start then low while running). You still may need to
replace your autocheck relay after relaying if its been too damaged, or
perhaps under the lighter, more consistent loading of the relay it will
still work, I don't know..
