Voltage drop during start

[rossiz]

been down that path, no luck it's so annoying having the clock constantly way off and it's such a pain to re-set (multiple submenus and fiddly/fussy controls) that i don't bother with it anymore - almost ready to put electrical tape over the display to make it go away - heck, i KNOW what my 5 preset stations are... the radio works, but other than that i'm unimpressed and wouldn't recommend it.

Yeah, I figured, but I had to ask. So one more far fetched possibility... In the old days they used to put a small hole in the chassis of stuff like that to adjust the clock. I guess there's a tiny chance that you've got something like that? Maybe covered by a sticker?

And lastly, have you talked to Retro about the issue? There's no way you should be off by 10 min/week. There's a problem there that should have been caught in production testing.

Hey guys,

 

 

Sorry for the huge delay in status updates.  I was having engine rebuild issues but finally those are dealt with and back to the minor issues I was having before.

I just took the radio out once again.  I did a small test on the voltage from from the yellow constant 12v wire.   When I turn the key on to ACC, and have my electric fans on, and the fuel pump on the voltage would drop to ~11.95v.  If I did the same test, with a wire directly from the battery it would read 12.2v.

I also tested the drop while start the engine and it was down to 10v on the wire I'm currently using (I did not test with the direct 12v source from battery) but i'm hoping the drop may be enough the radio is losing power.  I will run a temporary line to the starter, and connect it to the yellow content.   Fingers crossed and hoping for the best.  For now it's lunch time.  Update to come.

Well, my 12v source directly to the battery did not work.  I tested the voltage drop while starting the battery on this new direct line.  It is still down to 10 volts or so.   I was looking back at my emails at Retrosound stated a voltage drop of less then 12v can mean a dying battery (Mine is new), and may lead to the stereo not retaining it's memory.

I have 1/0 gauge (Yup, thats right) battery terminals leading to the engine ground, and the starter.  What else could this voltage drop be caused from?
