Hi, Have an LV ABA set #20-2241-1 that I bought used off the Internet. It was supposed to run great. I put a new battery in the lead A-unit & lubed it. It does seem to run well by itself (in conventional) but the only noise it will make is a screeching noise, (no bell, no horn, no engine sounds) whether moving or in neutral. It pulls between 1.8 - 2.1 amps at 16v on my Z4000 while moving. Lights work ok, etc. Where should I start to investigate my noise issue ?
A second question, I did not see in the owners manual if the rear A unit was a stand-alone engine or could only be run as an ABA set ?
Thks,
Rich
