May be in wrong forum, but here goes:
Troubleshooting an old "plastic sign" using F72T12CWHD tubes
Uses one ballast for 4 tubes (24 feet), only three tubes light
one ballast for 5 tubes (30 feet), only three tubes light
On some parts of sign a single tube will ignite (parallel)
On other parts, pairs of tubes must ignite togather (series)
Without diagram I'm lost as to relatioships between tubes.
Need diagram of wiring including the ANSI C82.1 color codes
Found one source (Advance) but their print too faint to read
Can anyone help or point me to a clear source for wiring, that on ballast is too faded to read and I'm told that this style ballast is being phased out.
