I just solved a problem involving my lilliput and I thought I should post it in case it can help someone.
I installed the lilliput temporarily and connected the power to the cigar lighter. I soon find out that my system that never had a noise before now has a serious alternator whine.
I cut the wire and connected ( both 12v and ground) to the distribution block were the inverter/ITPS combo are connected. The noise remained.
Finally I did what I planned from the beginning and didn’t do because of the temporary nature of the installation, cut the egg regulator off and wired the power ( 12v and ground) directly to one of the 12v connectors on the ATX PSU. Cool.. Noise no more...
My system:
Distribution block to bat
ITPS connected to Distribution block and acc and controlling a relay.
Inverter with the 12v from the Distribution block thru the relay.
All with common ground on a bolt and less than 30 cm cable.
AMD board with 90W atx psu, vga and onboard sound, 3.5 HDD and no optical drive.
Onboard sound connected to aux in, on head unit.
7" Lilliput.
Now working smoothly
