Icom IC-M710 Installed

We installed the Icom IC-M710 SSB a cruisers cell phone today, well I should say it just didn't happen today but over a period of months.  A cost of $1000 for the radio and $292.13 for the coax, etc...  It receives just fine but no SWR reading even though the automatic tuner is setup according to the automatic instructions, my SWR meter, that I inherited from my grandfather (Walter Grimmer, sure wish he was here to help me, he'd have it fixed in a jiffy) doesn't seem to pick it up when plugged in (broke???).  The bilge light comes on when transmitting, so it must be working according to everything I've read, lol!  I've listened to WWV in Fort Collins, CO; Mississippi; and Florida.
