Testing Heater Voltage - All BP Systems
CAUTION - TEST IS WITH POWER ON.
Testing at the heater terminal verifies that
there is not a broken line to the heater. It
may also indicate problems that may not
be apparent visually, such as corrosion or
a damaged heater terminal post.
However, before you do test, read on...
AVOID TOUCHING THE HEATER ASSEMBLY
WHILE PERFORMING THIS TEST.
THE HEATER IS ATTACHED TO GROUND.
Many people use probes to test live heater voltages
from TB1 to a heater post, or across both posts.
DON'T.
There is danger in measuring voltages across
heater posts. Some of the common problems in
testing spa systems are that:
The area is often tight and confined. 1.
The area is often not well lit. 2.
Spa control systems are usually placed at near 3.
ground level, which makes measuring with
meter probes awkward or difficult. The probes
may have a tendency to slip or not touch the
designated point of test. If a probe slips and
simultaneously contacts a hot (240V) post and
ground, severe arcing will occur. DEATH OR
SEVERE INJURY CAN OCCUR.
