Hi Arthur,

Let me say that I really do appreciate your assistance. And I beg your patience inexperience here - I'm somewhat mechanically savvy, but I must admit the electrical side of things is not my forte.

Anyway, I THINK I understand some of what you just told me. I did some of what you suggested, but couldn't do all (as I'll explain):

1. In relay box - female terminals 85 & 86 - I get 5 volts.

2. I replace fuse 7 with brand new fuse (again) - still get 5 volts.

3. I confirm that relay coil contact remains OPEN (with engine first turned on) - and pump clutch does NOT engage.

4. I then manually close relay coil contact - and pump clutch engages.

The 2 things you suggested I do, but could not or did not do (tonight) are:

5. Ohms reading on relay posts - I get no reading. HOWEVER, I'm not sure my meter is operating correctly, as I get no response even touching meter prongs.

6. I did NOT apply 12 volts across relay terminals 85 and 86 BECAUSE female terminal readings were 5 volts, and I wasn't sure if I should apply as much as 12 volts. (The relay cover states it is for 12 volts - but I thought this might just apply to the load, and maybe not to the coil voltage).

So, do my partial tests indicate anything? If not, I'll figure out how to get a ohms reading tomorrow.

Thanks again!

Jim
