Not sure if I'm allowed in Canada, I've been told Drunk Driving offenses count as felonies over there and they don't let "felons" in
It was a long trying week, glad to have some down time this weekend.Nice to see you back at it Zeb, I have Merlyn running ltspice sims on a SA-8800 to see why we have one oscillating
So. I was reading about a few things in other threads and realized that I am a bit out of my depth on this one. For safety's sake, I am just going to have a tech do this job. Thank you for the reply.Only three pins on each side of the modules are used. 0, 1, 2 and 7, 8, 9.
Measure the DC voltage at those pins. Plus and negative voltages are expected. Some maybe less than one volt.
Report the readings.
Oh I am tremendously interested. The reasoning behind my knee jerk is that I was reading another thread from about 10 years where someone was asking the exact same questions and the guy answering got really alarmed and just told him to close it up because he was not going to be part of his electrocution. So I took that to heart a little. I will have to watch some more videos to make sure I get it down. I got a kiddo on the way and I can only take so much of that current, ya dig?Read up on the use of a DMM. In this case, reading DC voltages. Practice on a battery. The black probe is grounded to the chassis and the red probe contacts the pins on the module. Tape up the red probes metal tip so only a small amount of metal tip is exposed. This will prevent the probe from contacting two pins at the same time (Bad). A steady hand is still required. Have someone else read the meter, that way you can concentrate on the matter at hand.
You do need a descent meter to read the voltages accurately. Some of the guys have said the Harbor Fright meter isn't too bad.
You got this far, you must have some interest/knowledge, why stop now?
At the very least, you'll know whats wrong with it.
