(DG) P70 connect to SPX30 computer

Hi sailcrazy

Thankyou for your enquiry.

Check that you have 12v measured across the 0volt and 12v connected to the p70? has the SeaTalk fuse blown? ( although this is odd considering the ST7001 powers up!)

Check the p70 by applying 12v directly to the red wire and 0volt directly to the screen/black wire ( depending which cable you are using, the 0volt will be the bare shield wire or the black ground wire)

If the control unit powers up and the Fuse in the computer for SeaTalk is good, then there must be a further fault within the SPX30

Have you tried both SeaTalk connections?

regards
