Should I have 5 volts in turn signal circuit?

[siggyfreud]

Hey all,

Trying to diagnose and fix issues with new headlights I've installed. I have another thread about the headlights, but I in doing so I have a general question.

With my turn signals off, but park lights on, should I be seeing 5.5 volts in the turn signal circuit?

If I pull wiring from a front turn signal or side marker and put the park lights on, the park light wire reads 12v as expected. However, the turn signal wire reads 5.5v at the same time. Is this normal?

Cheers all.
