Product Introduction
Sperry Marine 65801801-13B is a radar trigger PCB used in BridgeMaster and related marine radar systems. It manages scanner timing and trigger pulses, which is why it matters when the radar has timing faults or no proper sweep response.
This part is bought as a direct replacement for legacy shipboard radar hardware. Confirm X-band or S-band setup, revision, and connector layout before installation, because trigger boards are sensitive to system variant and matching logic.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Radar sweep does not start | Trigger PCB fault or timing signal loss | ✅ High | Check trigger output and scan timing at the board | If power is stable and timing is missing, replace the board |
| Radar image is frozen or inconsistent | Failed trigger pulses or connector issue | ✅ High | Inspect pulse activity and reseat connectors | Recheck wiring before condemning the PCB |
| X-band or S-band radar does not respond correctly | Wrong variant or band mismatch | ✅ High | Verify the band type against the installed radar | Match the exact board variant before power-up |
| Radar boots but never scans | Trigger circuit failure or upstream control issue | ✅ High | Compare the scan start signal with a known-good unit | If the signal is absent, the trigger board is suspect |
| Intermittent sweep timing | Loose connector, aging components, or heat stress | ✅ Medium | Run the system under load and check for thermal drift | Clean contacts and retest before replacement |
| Other radar sections work, only trigger function fails | Local board fault | ✅ High | Check adjacent modules and confirm the fault follows the board | Replacement is likely if the fault stays with this PCB |
Contact technical support with photos of the label, connector side, and any diagnostic logs if the fault is still unclear.
Frequently Asked Questions
Q: Is 65801801-13B a trigger PCB?
A: Yes. It is listed as a Sperry Marine X/S-band trigger PCB used for radar scan timing and trigger control.
Q: Is this new or used stock?
A: The listing I found describes it as reconditioned, not factory-new. That means it should be tested, but it is not fresh OEM stock.
Q: Does it work with both X-band and S-band radar?
A: Yes, the listing describes X-band and S-band compatibility. Still verify the installed radar variant before ordering.
Q: Can I swap it without reconfiguring anything?
A: Sometimes, but only if the radar family, revision, and connectors match exactly. Trigger boards are timing-critical, so verify the old board details before power-up.
Q: Why is reconditioned cheaper than new?
A: Because it comes from recovered stock instead of current OEM production. The lower price is useful, but you should still ask for test confirmation and warranty terms.
Q: What is the main installation risk?
A: The main risk is using the wrong band or revision. ❗Do not wire from memory. Confirm the exact part number, radar family, and connector positions before energizing.
Q: Does it come with a warranty?
A: The listed source says 3 months. For this kind of board, get the warranty terms in writing and confirm what test standard was used before shipment.
