VP MD2030 "D" wiring issues

[Hoist]

Recently I bought a VP 2030 "D" with low hours and I thought I could easily convert it to shaft using the parts from my Perkins Perama M30

Both are based on the same Shibaura block but due to the difference in engine mounts I had to use the old Perkins alternator as the VP is totally different and mounted differently

I thought it would be a case of matching the wires from the 2 wiring diagrams however we have hit a snag

When we have wired it all up the engine starts and runs perfect however the buzzer stays on.

Also all of the warning lamps stay on.

Does anybody see a problem with my wiring?

I think my problem lies with the Red/Blue wire being hot when it shouldn't be

What is D+61 and W mean on the Volvo alternator? My perkins one doesn't have that

I've attached 2 pics of my VP alternator and one my Lucas/perkins alternator (lucas perkins is blue)

Any help is appreciated.

Trying to work out - what Control Panel do you have ? - VP ?

VP non ignition key

If you have the VP control / Alarm Panel - the BL/R is effectively the power supply - so will be live all the time - its powered from the voltage on/off button and links via the Alarm Test / Glow Toggle switch.

you need BOTH sides of the Drawing in the manual - Page 9 and Page 17 - (depending what control Panel you have)

this might assist ? - from search on Excitation Resistor -

On the D+ terminal (top of alternator on a 2030) there is a another output which has a brown and red/blue cable. This reads the alternator output and drives the warning light / buzzer on the engine panel via the brown cable. Check this. It should be 12v+ Below 11V it will probably fire the alarm. It also provides excitation current to make the alternator start (Blue / Red via a 33ohm excitation resistor in the black box).

If you have 12.5v+ on that pin, yet the buzzer is sounding your issue is upstream of the alternator. Next check the multiconnector under the engine black box and the engine panel. Contact cleaner is useful. If you check the engine panel loom you will have a Brown wire to the block that has the warning lights. Check the voltage there. If its 12.5v+ and the panel is buzzing/alarming its probably the diode block. I have a spare (don't ask) you could try.

Does the light light as well buzzer?

If its buzzing and 11v or less, you alternator might need some attention. There are usually local (car) specialist who can check or recondition for allot less than a new one. Parts4engines do reasonable priced new ones if you need one urgently.


ANOTHER THOUGHT from the above - The VP Alternator has an Excitation Resistor - - I cant see any such thing required for the PERAMA Alternator in the wiring diagram - so it might be that the PERAMA Self excites. - I.E Don't need the BL/R.

if you want to MEASURE whats going on on GHOSTER - message me. (VP MD2030, VP ALT and VP non Key Panel)

Andy T to the rescue.

Nothing wrong with my wiring at all ?

Fault diagnosed as a bad warning module in the start panel
