Not a help for the brake light problem but the 5 amp will have voltage when the headlights are on and will vary in voltage by the setting of the headlamp switch dimmer (for dahs lights).

Tony,

First, do your Emergency flashers work? The brake lights and the emergency flashers share the same 15 amp circuit breaker. If they work, test the brake light switch to make sure the switch is working properly. Note if you have recently converted your brakes from manual to power, you need to replace it with a power brake specific switch,

The 70 Cougar brake Circuit 511 (green) splits from the brake light switch, one goes directly to the Sequential unit in the trunk and the other goes to the turn signal switch. The 511 circuit in the turn signal switch is routed internally to internal circuits 9 and 5 and outputs from the turn signal harness as circuits 442 and 445. 442 and 445 are then fed back to the sequential unit as well. Note at the sequential harness connector, 442 and 445 branch directly to the left inner (442) and right inner (445) taillights. You need to make sure that all 3 of these circuits are powered when the brakes are activated.

This is very true, few years ago when I experienced a similar problem with brake lights not working properly while everything else was OK, I solved the issue by replacing old manual brake light switch with new power brake light switch + I abraded all sockets and bulbs to ensure best possible contacts.
