The fuses all test good.
Everything is clean at the battery terminals.

When it occurs, I get 7volts on all the affected circuits. Same voltage every time.

When a load is applied,
sometimes it will cause the circuits to come to full voltage,
sometimes it will cause the circuits to drop out completely.

Repeatedly cycling the ignition key off and on will eventually result in full power to the circuits.

What relay, if failing, would cause a low voltage condition on some of the car's circuits ?
