-# LAB-003 — Truck Battery Disconnect Install Packet
-
-No battery disconnect switch has been purchased or installed yet.
-This packet turns the issue into a field-ready purchase / install / validation checklist while preserving what still requires live work.
-
-## Candidate Store Run
-
-- AutoZone — Newport or Claremont
-- Advance Auto Parts — Newport or Claremont
-- O'Reilly Auto Parts — Newport or Claremont
-
-## Required Items
-
-- battery terminal disconnect switch
-- terminal shim/post riser if needed
-
-## Selection Criteria
-
-- Fits the truck battery post without forcing the clamp
-- Mounts on the negative battery terminal
-- Physically secure once tightened
-- no special tools required to operate
-
-## Live Purchase State
-
-- Store selected: pending
-- Part selected: pending
-- Part cost: pending purchase
-
-## Installation Target
-
-- Install location: negative battery terminal
-- Ready to operate without tools: yes
-
-## Install Checklist
-
-- [ ] Verify the truck is off and keys are removed before touching the battery
-- [ ] Confirm the disconnect fits the negative battery terminal before final tightening
-- [ ] Install the disconnect on the negative battery terminal
-- [ ] Tighten until physically secure with no terminal wobble
-- [ ] Verify the disconnect can be opened and closed by hand
-
-## Validation Checklist
-
-- [ ] Leave the truck parked with the disconnect opened for at least 24 hours
-- [ ] Reconnect the switch by hand the next day
-- [ ] Truck starts reliably after sitting 24+ hours with switch disconnected
-- [ ] Receipt or photo of installed switch uploaded to this issue
-
-## Overnight Verification Log
-
-- Install completed: False
-- Physically secure: False
-- Overnight disconnect duration: pending
-- Truck started after disconnect: pending
-- Receipt / photo path: pending
-
-## Battery Replacement Fallback
-
-If the truck still fails the overnight test after the disconnect install, replace battery and re-run the 24-hour validation.
-
-## Missing Live Fields
-
-- store_selected
-- part_name
-- install_completed
-- physically_secure
-- overnight_test_hours
-- truck_started_after_disconnect
-- receipt_or_photo_path
-
-## Honest next step
-
-Buy the disconnect switch, install it on the negative battery terminal, leave the truck disconnected for 24+ hours, and only close the issue after receipt/photo evidence and the overnight start result are attached.
