What Transfer Delay Tells You about a Standby Generator Fault

A demonstration field guide for a start that succeeds but transfer never corresponds using start-to-transfer timing against the controller setting before replacing the transfer correspondence path.

This demonstration guide answers one field question about a start that succeeds but transfer never corresponds. Measurements come before parts, and the notes are not a generic equipment FAQ.

Diagnose before replacing parts

Start with start-to-transfer timing against the controller setting. That reading separates a start that succeeds but transfer never corresponds from adjacent faults that share the same complaint.

If the measurement is out of spec, treat the transfer correspondence path as the primary path. If it is in spec, do not replace the transfer correspondence path just to complete a parts list.

Repair the failed system

The usual correction is the transfer correspondence path, installed to the documented spec for this complaint.

A demonstration shop records the finding so the next technician is not repeating a guess about a start that succeeds but transfer never corresponds.

Stop before you make it worse

Do not forcing an immediate transfer while voltage is still unstable. That shortcut hides the original measurement and creates a second failure.

If the machine still fails after the transfer correspondence path is corrected, convert the visit to a broader diagnosis rather than stacking parts.
