Hey all - got a gm-h200 no output. Final turn on relay not switching. I cant remember (I've had this on a coup[le others in the past) I'm not an idiot-but prior to no output, it would hiccup like it was going into thermal - soooo I checked for cold solder, etc. re-soldered bunch of stuff. Now no final relay turn on - fan runs, etc- no output and no magical relay "click"
Help ??

Hi
Check if power light is ON, check the input selector that is correct for your cable,
check the drive mode switch.
There is a lot of cabling to check,
Check cabling for power - there is a low tension side
to connect first comprised of a Yellow and Black cable connected to the vehicles
light circuit for illumination of controls there is a red and black wire connected
to the ignition switch.
For the high tension two Black cables connect to vehicle chassis - closer to battery
is better, and two red cables to battery positive - all have fuses, that should be checked

Does the amplifier produce clean audio at the input to the relay for both channels?
If so, post the DC voltage on all pins of IC601.

Perry, Thanks for the help on this==
Alll voltages DC input voltage from PS=13.3vdc
1=0.0 2=0.0
3=11.4 4=0.114
5=0.65 6=0.0
7=6.83 8=0.0
9=0.055 10=13.2
11=0.05 12=13.2
13=13.25 14=12.8
15=0.0 16=0.0
this is where I start to become not as educated as I'd like to be == according to the schematic I have, it looks like I have some eroneous voltages as well as some incorrect voltages ? Thanks again- BTW your website rocks
Unfortunately the only test equipment I own is a very nice multimeter - and a tone generator on my laptop
I look forward to your response, and (hopefully)extended help, Dave

I'll get back to it tonight or Sat- Thanks == and no, that was in regards to post #3 == Havent pulled the cap yet
If you have a PDF copy of the service manual for the H200, email me a copy. Otherwise, I'll have to wait until I get back to the shop where I have a paper copy.

Do you have another amp open to compare the resistance from pin 5 to pin 8?
Without the capacitor (c602), the defective amp may get to the final reading before the normal amp. Black probe on pin 8 if you can do this. Do this with no power applied.

Do you have any of the H-series amps? They use the same basic circuit.
The reason I want you to compare the readings is because I cannot find anything wrong with the inputs to the control IC.

on a gm-h50 I have the same reading w/ black probe on pin 5 as the 200=(4.4M ohm)===
When I do black probe on 8 on the 200, I get an open

my thoughts exactly - I have one on order already - I ran out of braid so I gotta wait either way. I'll drop a line back when I get the new IC swapped in. I downloaded the data sheet for it and I'm thinkin the IC is toast
Finally got the parts and time to get back to this ! replaced IC601 and it performs flawless once again --- Thanks Perry for the help !
