ok I got a working but used python car alarm
I hooked up the wrong (not main) ground wire
then I hooked up the power whoops!
the siren went off very quietly
by the time I figured it out and hooked up the real ground
it didn't work anymore
is this thing repairable or is it another in a string of lessons
A.K.A. spare parts
there is no visible damage
I'm thinking shorted I.C. or transistor
does anyone know how to test these?
if anyone is interested I will post the part numbers on the IC's
and transistors

ok I looked up the numbers off the IC's and transistors
but couldn't find any information I don't know if they are part #s
the 28 pin # is DEI63T A426K0894
the 16 pin # is M'SIA 0413U ULN2003A
1 transistor is K A1046 Y 423
there is an NEC D882
and a cube with OEG MCL-112D2H
I was trying to price these to see if it's worth fixing
all I can do is replace parts other than simple tests I am lost
if no one thinks it's worth the effort to repair
I may give up and buy another brain box
