Wira Horn problem

[ylkien]

Hi guys,

Just wondering whether has anyone experienced this before....

Changed Wira horns to Hella brand. Old horns still working, but sound has "deteriorated".
When both Hella horns is connected, no sound.
But when either Hella horn is connected, there is sound. (no polarity)
Voltage check reveals a drop to ~8V (from 12.4V) when single Hella horn is active.
Hypothesis, voltage too low to activate both Hella horn together.


Please share your experience.
Arigatou.
