Engage starter, radio shuts off for a split second??

[mountie]

It did it once yesterday, once today.... I turn ignition to start, and starts up fine....
But I notice, during the 'start', the radio looses power for a split second then stays on. ( I don't know what else shuts off also - yet)
Battery shows a good charge, no other issue - yet?

Any suggestions??? 2005 Yukon 5.3

That's always been the case with every vehicle I've owned. They cut power to all other accessories since the starter has such a draw.

Radio on, while starting as usual, but this is a bit different.. The radio clock changes time, as if power is disconnected.

I'd have the battery load tested, and check the condition of both battery cables and ground connections. Battery-body-engine grounds and positives.

Sounds to me like the supply voltage is dropping enough to affect the clock.

Ahh, I thought you meant the usual radio goes off while cranking. Not actually losing power. Got it now. Yep, as Fless said, load test and check all your cables, grounds, connections, etc.

Thanks..... even though my battery is 6 months old, and cables have been checked before, ..It is a "vehicle" and things do change......I will check again.
A few months ago, I bought an ignition module due to a previous concern. ( I wonder if this is a concern ?) Starting has been fine....

Pull both cables at battery and check/clean and reinstall and then go to ends of cables and do the same. Will likely fix concern. If not, sell it and get another.

I tightened the battery negative.... It wasn't loose, but it wasn't REALLY completely tight.
I think it's resolved...... I think......
