Hello member,
All my gauges on Mariah 2006 SX 18 are not working. I took my boat to repair shop, they told me i need new alternator, they change the alternator and told me all gauges are not working. Does anyone knows why changing alternator will cause all gauges to stop working?
How much it would cost to change all gauges and where i can order these gauges?

I doubt very much that changing out the alternator caused your gauges to fail. More likely someone has failed to reconnect a power or ground wire or a fuse has burnt out.
